The 1912 PCHA season was the first season of the now defunct men's professional ice hockey Pacific Coast Hockey Association (PCHA), a league founded on December 7, 1911. The three teams, all based in British Columbia, Canada, were to play a sixteen-game schedule, but one game was cancelled. The season ran from January 2 to March 19, 2012, ending with the New Westminster Royals as the first PCHA champions. In February, the PCHA had issued a challenge to the two-year-old National Hockey Association (NHA) to have the two leagues' champions play a series for the Stanley Cup, but the season ended too late for the Royals to travel east to face the NHA champion Quebec Bulldogs, who retained the Stanley Cup without further challenge for the 1911–12 season.

The Pacific Coast Hockey Association (PCHA) was a professional ice hockey league in western Canada and the western United States, which operated from 1911 to 1924 when it then merged with the Western Canada Hockey League (WCHL). The PCHA was considered to be a major league of ice hockey and was important in the development of the sport of professional ice hockey through its innovations.
