The 2013 Jacksonville Jaguars season was the franchise's 19th season in the National Football League, the first under general manager David Caldwell, and the first under head coach Gus Bradley. Although they missed the playoffs and started 0-8, the Jaguars improved upon their franchise-worst 2–14 record from 2012; but failed to improve their 1-7 home record from last year. Much like 2012, the root of their victories were intra-division. The Jaguars also gained a close non-divisional victory over the Browns to finish 4-12.
