2019 West Coast Conference men's basketball tournament

[1] Saint Mary's upset top-ranked Gonzaga 60–47 in the championship game and received the conference's automatic bid to the 68-team NCAA tournament.

With the loss, Gonzaga fell to fourth in the national rankings, but was still the top seed in the West regional.

The tournament returned to a format similar to that used from 2003 to 2011, with slight changes to the terminology used for the rounds prior to the semifinals.

As the regular-season champion, Gonzaga clinched a semifinal spot, and technically secured a place in the NIT.

Saint Mary's also clinched a semifinal berth as the regular season runner-up.
