The 2015 NHL Stadium Series was an outdoor regular season National Hockey League (NHL) game, part of the Stadium Series of games held at football or baseball stadiums. The Los Angeles Kings played against the San Jose Sharks at Levi's Stadium in Santa Clara, California on February 21, 2015. This was the only game in the Stadium Series during the 2014–15 NHL regular season. The game coincided with NBC Sports' "Hockey Day in America" coverage, and aired on NBCSN in the United States, while it was the second game of CBC's Hockey Night in Canada doubleheader.

The Stadium Series is one of the series of regular season outdoor games played in the National Hockey League (NHL). This event is distinct from the NHL's other two series of outdoor games, the NHL Winter Classic played on New Year's Day in a different NHL city every year, and the NHL Heritage Classic. Games in the Stadium Series have been held in either late January, February, or early March in a football or baseball stadium in the United States. The first Stadium Series was held in 2014 and consisted of seven teams participating in four games held in three venues. In 2015, only one game in the Stadium Series was held, while in 2016 and in 2024, two games were held. From 2017 to 2023 and again in 2025, only one game was scheduled per year.
