As Arizona prepares to play in its 22nd all-time Sweet Sixteen on Thursday, we’ve compiled a list of all such appearances by schools in the West.

The region boasts 37 Sweet Sixteen teams, 29 of which have made two or more appearances, led by UCLA, Arizona, and Gonzaga.

But before we get to the list, for those who may be interested, a little history.

The NCAA recognizes Sweet Sixteen appearances since the first tournament, in 1939, even though only eight teams played the tournament from 1939 to 1950.

Between 1951 and 1952, there were sixteen teams in the tournament, so all could claim a Sweet Sixteen appearance.

The team counts fluctuated from 22 to 25 between 1953 and 1974, and some of those teams received byes to the Sweet Sixteen.

However, from 1975 to 1984, all teams were required to play at least one game before the Sweet Sixteen, and since 1985, all have been required to play at least two games.

Here is the list of participating schools from the region.
