The 2017 Pac-12 Conference men's soccer season was the 18th season of men's varsity soccer in the conference. Stanford, who entered the season as the three-time defending Pac-12 champions, successfully defended their title for the fourth consecutive season, by winning the regular season (there is no conference tournament). The Cardinal were also the two-time defending NCAA champions, and successfully defended their title. California and Washington earned at-large berths into the 2017 NCAA Division I Men's Soccer Tournament, but were both eliminated in the first round.
