1986 Southwest Conference baseball tournament

The 1986 Southwest Conference baseball tournament was the league's annual postseason tournament used to determine the Southwest Conference's (SWC) automatic bid to the 1986 NCAA Division I baseball tournament. The tournament was held from May 16 through 19 at Olsen Field on the campus of Texas A&M University in College Station, Texas.

Due to rain delays, the loser's bracket and semifinal games were canceled, resulting in the winners of the first round games advancing directly to the finals.

The number 2 seed went 3–0 to win the team's first SWC tournament under head coach Mark Johnson.

Format and seeding
The tournament featured the top four finishers of the SWC's 8 teams in a double-elimination tournament.
