The 1975 Miami Dolphins season was the franchise's tenth season in existence, and its sixth in the National Football League (NFL) since the AFL-NFL merger.
Although Miami tied for the AFC Eastern division title at 10âÂÂ4 with the Baltimore Colts, the Colts won the divisional tiebreaker in 1975 with a sweep of both inter-division matchups, beating Miami 33âÂÂ17 in week 10 and 10âÂÂ7 in week 13. The sole wild card in the conference was Cincinnati at 11âÂÂ3, so the Dolphins missed the playoffs for the first time since the merger.
The 1975 Dolphins were without running backs Larry Csonka and Jim Kiick and wide receiver Paul Warfield, who each signed three-year contracts with the Memphis Southmen in March 1974 to play in the World Football League, beginning in 1975. The second-year league folded in the season's twelfth week, and the trio returned to the NFL in 1976 with other teams.
