List of All-Pac-12 Conference men's basketball teams

The All-Pac-12 men's basketball team is an annual Pac-12 Conference honor bestowed on the best players in the conference following every college basketball season. Pac-12 coaches select a 10-player first team and a five-player second team. From 1956 through 1977, there was one five-man team first team. There were two five-man teams in 1978 and 1979, followed by one 10-man first team from 1980 through 2008. For one year in 2008, there were three five-man teams selected.

During the final week of the regular season, Pac-12 coaches nominate up to three players from their team to be placed on the ballot for consideration. Coaches submit their votes by the Sunday after the season ends and cannot vote for their own players. Previously, a player needed to be selected on 50 percent of the ballots to be on the team. In the 2006–07 season, only nine players received enough votes to be selected. Ties resulted in extra players being selected in some seasons. Each team member receives an award. Players who are not placed on the first or second teams, but received at least three votes, earn honorable mention. The Pac-12 staff has the right to add to list of recipients selected by the coaches for recognition.

The Pac-12, as currently chartered, was formed in 1959. However, the league claims the history of the Pacific Coast Conference (PCC), founded in 1915, as its own. After the collapse of the PCC in 1959, five of its members immediately founded the Athletic Association of Western Universities (AAWU). By 1964, all of the final PCC members except Idaho were reunited in the AAWU. The AAWU unofficially used the names Big Five, Big Six, and Pacific-8 before formally adopting the "Pacific-8" name in 1968. The name changed to Pacific-10 when Arizona and Arizona State joined in 1978, and to Pac-12 when Colorado and Utah joined in 2011.
