Pierce George "Gerry" Geran (August 3, 1896 – September 8, 1981) was an American ice hockey player. The first American-born player in the National Hockey League (NHL), he appeared in four games with the Montreal Wanderers in the NHL's first season, 1917–18. He would later play one season in France, the first American to do so, and spent several years playing in the United States Amateur Hockey Association. He returned to the NHL in 1925–26 with the Boston Bruins, and finished his career one season later in the American Hockey Association. Internationally Geran played for the American national team at the 1920 Summer Olympics, the first Olympics to feature ice hockey, and won a silver medal.
