2011 Detroit Lions season

The 2011 season was the Detroit Lions' 82nd in the National Football League (NFL), their 78th as the Detroit Lions, their 10th playing home games at Ford Field and their third under head coach Jim Schwartz. With a regular season record of 10–6, the team improved on their 6–10 record from 2010, making it their third consecutive improved season. It was the Lions' first winning season since 2000 and first 10 win season since 1995. Their 10-win season came just three years after their winless 2008 campaign. The Lions' 5–0 start was their best since 1956. With their win over the San Diego Chargers on December 24, the Lions clinched an NFC Wild Card spot in the postseason. After their loss to the Green Bay Packers in Week 17, it was determined the Lions would play the New Orleans Saints in one of the NFC Wild Card Games, which the Lions lost 45–28. It was their first playoff berth since 1999.

The Lions ran a pass-heavy offense in 2011, mainly due to early injuries of running backs Mikel Leshoure, who was injured in the preseason and Jahvid Best, who was injured with a concussion in week 6 against the 49ers. Kevin Smith was signed in November as running back, but he too was injured, this time a high ankle sprain during week 11 that inhibited his running. Quarterback Matthew Stafford's 663 passing attempts (41.4 attempts per game) led the league, and they only ran the ball on 33.8% of their plays, a league low. According to statistics site Football Outsiders, the Lions went into shotgun formation a league-leading 68% of offensive plays in 2011. Stafford became only the fourth quarterback to pass for 5,000 yards in a season, and his 5,038 yards passing are 5th-most in NFL history (though only 3rd in the 2011 NFL season).

The 474 points that the Lions scored in 2011 were the most in franchise history, until surpassed by the 2024 team, and only the second time that the team had scored 400+ points in a season.
