Pittsburgh Steelers head coach Mike Tomlin is the longest-tenured head coach in the NFL. He is entering his 19th season at the helm. In his first 18 years, he has compiled a record of 183-107-2, including two Super Bowl appearances in 2008 and 2010 and a win in Super Bowl XLIII during his second season as head coach.

On top of being the longest-reigning head coach in the NFL, Tomlin is now the longest-tenured head coach in all of major American sports.

San Antonio Spurs head coach Gregg Popovich is officially stepping down after an astonishing 29 years as the lead man on the Spurs’ bench, which now puts Tomlin in the No. 1 spot.

Tomlin has four years to go in order to tie Chuck Noll for the most seasons as the Steelers’ head coach, as Noll donned the headset for 23 seasons in Pittsburgh from 1969-1991. Tomlin’s contract runs through the 2027 season, which would get him up to 21 seasons. Whether or not he is brought back after that is a conversation for the future.
