Kent County is located in the U.S. state of Michigan. As of the 2020 Census, the county had a population of 657,974, making it the fourth most populous county in Michigan, and the largest outside of the Detroit area. Its county seat and largest city is Grand Rapids, Michigan’s second largest city. The county was set off in 1831, and organized in 1836. It is named for New York jurist and legal scholar James Kent, who represented the Michigan Territory in its dispute with Ohio over the Toledo Strip.

Kent County is part of the Grand Rapids metropolitan area and is West Michigan's economic and manufacturing center. It is home of the Frederik Meijer Gardens, a significant cultural landmark of the Midwest. The Gerald R. Ford International Airport is the county's primary location for regional and international airline traffic.

History The Grand River runs through the county. On its west bank are burial mounds, remnants of the Hopewell Indians who lived there. In the 18th century the Odawa migrated to this area and established multiple villages along the Grand River valley. By the 19th century there were estimated to be over 1000 Odawa. The fur trade became an important industry in the valley during the early 19th century. After the War of 1812, Rix Robinson and Louis Campau were the earliest traders in the area. In 1826, Campau established a trading post in Grand Rapids. In 1831, he bought land and platted the town. Campau is considered the town's "father". One year later, government surveyor Lucius Lyon purchased land north of Campau's property. Campau surveyed and platted the village following Native American trails and Lyon had platted his property in an English grid format, which meant there were two adjoining villages, with different platting formats. Campau later merged the villages under the name of Grand Rapids.

In 1831, it was set off from Kalamazoo County. In 1838, Grand Rapids was incorporated as the county's first village. By the end of the century, stimulated by the construction of several sawmills, the area was a significant center for agriculture, logging, and manufacturing furniture.
