|1972 Baltimore Colts season|
|Head coach||Don McCafferty
|Home field||Memorial Stadium|
|Division place||3rd AFC East|
|Playoff finish||did not qualify|
The 1972 Baltimore Colts season was the 20th season for the team in the National Football League. The Baltimore Colts finished the National Football League's 1972 season with a record of 5 wins and 9 losses, and finished third in the AFC East. Carroll Rosenbloom and Robert Irsay, who had recently taken over the Los Angeles Rams, traded ownership of the two franchises, with players and coaching staffs remaining intact. However, the Colts were getting older and started 1-4 before Coach Don McCafferty was fired. The Colts would go 4-5 in their final nine games under John Sandusky to finish with a 5-9 record, their first losing mark in 16 years.
On July 13, 1972, Robert Irsay bought the Los Angeles Rams and transferred ownership to Carroll Rosenbloom, in exchange for ownership of the Baltimore Colts.
The season began ominously for the Colts when they were defeated at home on opening day by the St. Louis Cardinals and their journeyman quarterback, Tim Van Galder. In week two, Johnny Unitas threw for 376 yards and three touchdowns, but it was far from enough as Joe Namath threw for 496 yards and six touchdowns to power the New York Jets to a 44–34 victory at Memorial Stadium, the Jets' first victory over the Colts since Super Bowl III.
In October, the Colts' season reached its nadir when it was shut out twice at home in a three-week stretch by the Dallas Cowboys, who undoubtedly wanted revenge for their loss to Baltimore in Super Bowl V, and the Miami Dolphins, who were on their way to a 17–0 season and their first Super Bowl championship under former Colts coach Don Shula.
Unitas made his final start in a Colts uniform in a week 12 victory over Buffalo.
For the third consecutive campaign, the Colts played their season finale in Miami's Orange Bowl. Only this time, it was a humbling 16-0 shutout to the Dolphins in Week 14 in a game which was nowhere near as close as the final score. Baltimore ended its 1970 season by defeating the Cowboys in Super Bowl V, and its 1971 season by losing to the Dolphins for the AFC Championship.
