The 2017 season was the Baltimore Ravens' 22nd in the National Football League (NFL) and their 10th under head coach John Harbaugh. This was also the 10th season with Joe Flacco as the team's starting quarterback. The Ravens improved on the previous season's 8–8 record, but failed to qualify for the playoffs for the third consecutive season because of a last second touchdown in a 31–27 loss to the Cincinnati Bengals, combined with a Buffalo Bills' victory over the Miami Dolphins in Week 17.
