The 2018 WAC men's soccer tournament was the 11th edition of the tournament. It determined the Western Athletic Conference's automatic berth into the 2018 NCAA Division I Men's Soccer Championship. The defending champions were Seattle U. However, they were unable to defend their title, falling 5–6 in a penalty shootout against San Jose State in the semifinals. The eventual champions were the Grand Canyon Antelopes, who won the tournament after a 1–0 victory over San Jose State in the final. This was the first WAC men's soccer title for Grand Canyon, and the first for coach Schellas Hyndman.
