The 2018 SEC women's soccer tournament was the postseason women's soccer tournament for the SEC. The Texas A&M Aggies were the defending champions, but they were eliminated from the 2018 tournament with a 2–1 loss to the South Carolina Gamecocks in the quarterfinals. The LSU Tigers won the tournament title via a penalty kick shootout win over the Arkansas Razorbacks in the final. This was the first SEC women's soccer tournament title for LSU, and the first for coach Brian Lee.
