The University of Arizona (Arizona, U of A, UArizona, or UA) is a public land-grant research university in Tucson, Arizona, United States. Founded in 1885 by the 13th Arizona Territorial Legislature, it was the first university established in the Arizona Territory. The University of Arizona is one of three universities governed by the Arizona Board of Regents (the University of Arizona, Arizona State University, and Northern Arizona University). , the university enrolled 54,384 students in 22 separate colleges/schools, including the Eller College of Management, the Wyant College of Optical Sciences, the College of Medicine – Phoenix, the College of Medicine – Tucson, and the James E. Rogers College of Law.

The university is classified among "R1: Doctoral Universities – Very high research activity". UA also is a member of the Association of American Universities. The University of Arizona is affiliated with two academic medical centers, Banner – University Medical Center Tucson and Banner – University Medical Center Phoenix.

Known as the Arizona Wildcats (often shortened to "Cats"), the UA's intercollegiate athletic teams were members of the Pac-12 Conference of the NCAA. The university joined the Big 12 Conference on August 2, 2024. UA athletes have won national titles in several sports, most notably men's basketball, baseball, and softball.

History

After the passage of the Morrill Land-Grant Act of 1862, the push for a university in Arizona grew. The Arizona Territory's "Thieving Thirteenth" Legislature approved the University of Arizona in 1885 and selected the city of Tucson to receive the appropriation to build the university. Tucson hoped to receive the appropriation for the territory's mental hospital, which carried a $100,000 allocation instead of the $25,000 allotted to the territory's only university (Arizona State University was also chartered in 1885, but it was created as Arizona's normal school, and not a university). Flooding on the Salt River delayed Tucson's legislators, and by they time they reached Prescott, back-room deals allocating the most desirable territorial institutions had been made. Tucson was largely disappointed with receiving what was viewed as an inferior prize.

With no parties willing to provide land for the new institution, the citizens of Tucson prepared to return the money to the Territorial Legislature until two gamblers and a saloon keeper decided to donate 40 acres to the Board of Regents. Construction of Old Main, the first building on it, began on October 27, 1887, and classes met for the first time in 1891 with 32 students in Old Main, which is still in use today. Because there were no high schools in Arizona Territory, the university maintained separate preparatory classes for the first 23 years of operation.

In 1924, during Cloyd Marvin's tenure as president, the university was recognized by the Association of American Universities.

Modern times The university hired its first African-American faculty member, Vivian Cox, in 1967.

Three professors were murdered at the school in a shooting in 2002. The perpetrator, who then shot himself, was a student who had failed out of the school. He mailed a 22-page letter to the Arizona Daily Star announcing his reasons, naming two of the killed professors in the letter; following the shooting, the Daily Star made the controversial decision to publish the letter.

On April 17, 2020, the University of Arizona announced temporary pay cuts and furloughs to its 15,000 employees as its Tucson campus shut down due to the COVID-19 pandemic. All employees making up to $150,000 per year were furloughed, with the length determined by each employees' salary. For employees making more than $150,000 per year, pay cuts of 17% or 20% were instituted.

Also in 2020, the University of Arizona announced it had purchased Ashford University from Zovio and renamed it The University of Arizona Global Campus. The purchase was heavily criticized, particularly by University of Arizona faculty members. As Ashford was being purchased by the University of Arizona, it was the subject of an investigation by the Attorney General of Massachusetts, a lawsuit from the Attorney General of California, and a formal notification of concern from the university's accreditor.

A university professor was murdered on campus in October 2022, by a former student. Following the crime, the university commissioned an independent investigation of campus safety. Following that investigation and one of their own that faulted the university for failing to act on warnings and protect the campus, the university's faculty senate voted "no confidence" in the president and many other leaders at the university.

In 2023, the University of Arizona faced a financial crisis, allegedly "losing track of more than $240 million through accounting errors and flawed financial projections." Subsequent investigative reporting by The Arizona Republic linked much of the crisis to the university's purchase of Ashford University, accusing university administrators of knowing that Ashford was experiencing "a downward enrollment spiral that began years before [the purchase] and dismal graduation and retention rates".

In April 2024, the UA chapter of Students for Justice in Palestine joined student protests across the USA against the war in Gaza, during what they called "Israeli Apartheid Week". The encampment was attacked and dispersed by police firing rubber bullets, tear gas and pepper balls. Bystanders and press were also hurt in the police violence. The students were protesting against UA involvement with companies supporting the "genocide and ethnic cleansing in Palestine" and called for divestment.

Campus

Physical campus The University of Arizona's main campus includes 179 buildings spread across in central Tucson, about northeast of downtown. The campus is roughly divided into quadrants. A broad grassy area known as the Mall separates the north and south sides of campus, stretching eastward from Old Main to Campbell Avenue, a major north-south street at the campus' eastern edge. Highland Avenue and the Student Union Memorial Center roughly divide the campus into eastern and western sections.

Science and mathematics buildings are concentrated in the southwest quadrant, while intercollegiate athletics facilities are located in the southeast. Arts and humanities buildings are mainly in the northwest quadrant, although the dance department is a notable exception, with its main facilities on the far east side of campus. Engineering buildings are concentrated in the north central area, while the optical and space sciences buildings are clustered on the east side near the sports stadiums and the main library.

Speedway Boulevard, one of Tucson's main east-west streets, traditionally marked the campus' northern boundary. Since the 1980s, however, the university has expanded beyond Speedway, constructing buildings on and north of the street in neighborhoods formerly dominated by apartment complexes and single-family homes. In recent years, the university has also purchased several apartment complexes for student housing. Sixth Street generally forms the southern boundary of campus, with many of the single-family homes south of the street rented to students.

A Computer Science department webcam provides a live view of the campus from the top of the Gould-Simpson building, the tallest classroom building on campus at 10 stories.

Architectural design and planning

Roy Place, a prominent Tucson architect, designed many of the campus' early buildings, including the Arizona State Museum buildings, one of them the 1927 main library, and Centennial Hall. Place's use of red brick established a visual style that still defines much of the campus, with nearly all University of Arizona buildings incorporating red brick either as a primary building material or as a stylistic accent intended to match surrounding structures.

Place's influence on the campus continued into the early 1930s, when he updated the campus master plan. The plan had originally been conceived in 1919 by his architectural partner John Lyman and was modeled after the University of Virginia.

Memorial and symbolic spaces

The Berger Memorial Fountain, located at the west entrance of Old Main, honors University of Arizona students who died in World War I and dates to 1919. Performance space The Stevie Eller Dance Theater, opened in 2003 (across the Mall from McKale Center) as a dedicated performance venue for the UA's dance program, one of the most highly regarded university dance departments in the United States. Designed by Gould Evans, a Phoenix-based architectural firm, the theater was awarded the 2003 Citation Award from the American Institute of Architects, Arizona Chapter.

Student Union Memorial Center The Student Union Memorial Center, on the north side of the Mall east of Old Main, was completely reconstructed between 2000 and 2003. It replaced a building that originally opened in 1951 and had been expanded during the 1960s and early 1970s.

Designed to resemble the , the building includes memorial features honoring members of the university community and others who served in the military. Memorial sculptures throughout the complex incorporate elements such as the sounds of chiming dog tags and refracted light. One of the center's best known features is the USS Arizona bell, which is housed in the building's clock tower. The bell was one of two recovered from the battleship after the attack on Pearl Harbor and arrived on campus in July 1946.

For decades, the bell was rung seven times on the third Wednesday of every month at 12:07 p.m., marking the time of the USS Arizona sinking on December 7, 1941. The bell was also rung after Arizona Wildcats football home victories, except against other Arizona schools. In December 2020, the university ended the long-standing ringing tradition after the U.S. Navy, which still owns the bell, requested that the historic object be protected from further wear. Arboretum Much of the main campus has been designated an arboretum. Plants from around the world are labeled along a self-guided plant walk. The Krutch Cactus Garden includes the tallest Boojum tree in the state of Arizona. Two herbaria on the university campus are referred to as "ARIZ" in the Index Herbarium.

The campus also boasts hundreds of olive trees many of which were planted by Prof. Robert H. Forbes. Many of these trees are over a hundred years old.

Sustainability and environmental design The University of Arizona generates renewable energy with solar panels (photo voltaic) that have been installed on campus buildings. In 2011, the Sustainable Endowments Institute gave the university a College Sustainability Report Card grade of "B." In 2015, the university opened the ENR2, housing the University of Arizona School of Geography, Development and Environment set to be one of its "greenest" buildings on campus with features like a cutting edge air conditioning system and 55,000-gallon water-harvesting tank. Designed to resemble a slot canyon in the Sonoran Desert, the 150,000 sq. ft. building focuses on adaptation and reducing our carbon footprint.

Organization and administration The University of Arizona, like its sister institutions Arizona State University and Northern Arizona University, is governed by the Arizona Board of Regents or the ABOR, a 12-member body. Eight volunteer members are appointed by the Governor to staggered eight-year terms; two students serve on the board for two-year appointments, with the first year being a nonvoting apprentice year. The Governor and the Superintendent of Public Instruction serve as voting ex-officio members. The ABOR provides "policy guidance" and oversight to the three major degree-granting universities, as provided for by Title 15 of the Arizona Revised Statutes.
