The 2011 season was the Baltimore Ravens' 16th in the National Football League (NFL), their fourth under head coach John Harbaugh and their 10th under general manager Ozzie Newsome.

The 2011 season marked one of the most successful seasons in Baltimore Ravens franchise history. The Ravens completed the season with a 12–4 record, matching their record from 2010, and winning the AFC North division title for the third time in franchise history. By earning a playoff berth in 2011, the Ravens set a franchise record by going to the postseason for four consecutive seasons. This was also the first and only season so far the Ravens went 6-0 in their division.

Over his first four years, Harbaugh compiled an overall record of 44–20 in the regular season and 5–4 in the postseason. The Ravens avenged their 2010 divisional round playoff loss against the Steelers in week 1 of the season with a big 35–7 victory at home. The 2011 campaign also marked the first time the Ravens played a Thanksgiving game: the Ravens played the San Francisco 49ers and won 16–6. (San Francisco was coached by John Harbaugh's brother Jim, and many dubbed the Thanksgiving game the "Harbaugh Bowl.") Coincidentally the Ravens and 49ers would meet next year in Super Bowl XLVII, which saw the Ravens win their 2nd title in franchise history.

After defeating the Cincinnati Bengals in week 17, the Ravens earned the first-round bye for the first time since 2006 as the second seed in the AFC. They won the Divisional Round against the Houston Texans but were defeated by the New England Patriots in the Conference Championship game, 23–20 after wide receiver Lee Evans failed to catch what likely would have been the game-winning touchdown on 2nd down and 1, and placekicker Billy Cundiff missed a game-tying 32-yard field goal attempt with 11 seconds remaining in regulation.

Linebacker Terrell Suggs was named Defensive Player of the Year.

Game summaries Regular season Week 1: vs. Pittsburgh Steelers

On the first play from scrimmage, Ray Rice scampered for 36 yards and would finish the game with 107 rushing yards, in the previous season the Steelers had given up an average of 62.8 rushing yards per game. Two plays later Joe Flacco threw a 27-yard strike to Anquan Boldin, giving the Ravens a lead they would never relinquish. Defense would be the story of this game, however, as Terrell Suggs strip-sacked Ben Roethlisberger during the Steelers second possession and Haloti Ngata recovered at the Pittsburgh 37-yard line. Suggs ended the game with 3 sacks and the Ravens forced 7 turnovers. With this win not only did the Ravens improve to 1–0, but they handed the Steelers their first opening day loss since 2002.

Week 2: at Tennessee Titans

With this loss, the Ravens fell to 1–1.

Week 3: at St. Louis Rams

Coming off a week 2 loss, the Ravens were determined to bounce back and fight hard. On their second offensive play from scrimmage, Flacco threw a 74-yard touchdown pass to rookie wide receiver Torrey Smith. It was the first catch of Smith's career and the longest pass of Flacco's. Before the first quarter was up, Flacco would throw two more touchdown passes to Smith for 41 and 18 yards respectively, marking the 12th time in NFL history that any receiver caught three touchdown passes in a single quarter, and the first time ever for a rookie. The Ravens would later add 16 more points on three Billy Cundiff field goals and a fumble forced by Ray Lewis and recovered by Haloti Ngata and then run into the end zone (Cundiff also missed two 51-yard field goals). This marked the first and as of 2018 only touchdown in Ngata's career. Offensively, the Ravens gained 553 yards in the entire game, a franchise record. The only score for the Rams came in the third quarter, when quarterback Sam Bradford threw a 34-yard touchdown pass to Brandon Gibson.

With this win, the Ravens improved to 2–1.

Week 4: vs. New York Jets

Coming off their dominating road win over the Rams, the Ravens went home, donned their alternate uniforms, and played a Week 4 Sunday night duel with the New York Jets. Baltimore delivered the game's opening punch with safety Ed Reed forcing a sack-fumble from Jets quarterback Mark Sanchez, allowing linebacker Jameel McClain to recover the fumble and go 6 yards for a touchdown. New York would respond with running back Joe McKnight returning a kickoff 107 yards for a touchdown. Afterwards, the Ravens regained the lead with a 38-yard field goal from kicker Billy Cundiff, followed by a 3-yard touchdown run from running back Ray Rice. Baltimore added onto their lead in the second quarter with another 38-yard field goal from Cundiff, followed by defensive end Haloti Ngata forcing a fumble from Sanchez, allowing linebacker Jarret Johnson to return the fumble 26 yards for a touchdown. The Jets responded with linebacker David Harris returning an interception 36 yards for a touchdown, followed by kicker Nick Folk booting a 40-yard field goal. The Ravens struck back in the third quarter with cornerback Lardarius Webb returning an interception 73 yards for a touchdown. From there, Baltimore's defense prevented any comeback attempt from the Jets.

With this win, the Ravens went into their bye week at 3–1.

Week 6: vs. Houston Texans

With stadium flags lowered to half-mast in remembrance of the passing of Pat Modell, wife of former owner Art Modell, the Ravens set the tone early with a 9-minute, 93-yard drive for a touchdown. Joe Flacco who scored on a quarterback sneak to cap the drive, also threw for 305 yards while Ray Rice ran for 101 yards. Ray Lewis became the first player in NFL history with 40 sacks and 30 interceptions when he sacked Matt Schaub in the first quarter. With this win, the Ravens improved to 4–1.

Week 7: at Jacksonville Jaguars

With this loss, the Ravens fell to 4–2.

Week 8: vs. Arizona Cardinals
