The 1990 Miami Dolphins season was the team's twenty-first season in the National Football League and twenty-fifth overall. After four seasons out of the playoffs with a combined record of 30 wins and 31 losses, the Dolphins returned to postseason play for the first time since 1985 with twelve wins and four losses. They defeated the Kansas City Chiefs in the Wild Card Game before being knocked out of contention by the eventual AFC champions, the Buffalo Bills, in the Divisional Playoff Game. As of 2021, this was also the last time the Dolphins finished with at least 12 wins.
