2023 Mountain West Conference women's soccer tournament

The 2023 Mountain West Conference women's soccer tournament was the postseason women's soccer tournament for the Mountain West Conference held from October 29 through November 4, 2023. The five-match tournament took place at Madrid Sports Complex in Laramie, Wyoming. The six-team single-elimination tournament consisted of three rounds based on seeding from regular season conference play. The San Jose State Spartans were the defending champions. The Spartans were unable to defend their crown, as they did not qualify for the tournament and finished last in the regular season. Utah State won the title after defeating Colorado State in the Final, 1–0. This was the first Mountain West tournament championship for Utah State. They previously won two championships in the WAC. It was the first title for head coach Manny Martins. As tournament champions, Utah State earned the Mountain West's automatic berth into the 2023 NCAA Division I Women's Soccer Tournament.

Seeding
The top six teams from regular season play qualified for the 2023 Tournament. Teams were seeded based on their regular season records. Tiebreakers were used to determine seeds if teams were tied on regular season record. However, no teams finished tied at the end of the regular season so no tiebreakers were required.
