List of players who played only one game in the NHL

This is a list of ice hockey players who have played only one game in the National Hockey League (NHL) from 1917–18 to the present.

This list does not count those who were on the active roster for one game but never actually played, or players who played one or more games in the NHL's predecessor, the NHA.

‡  The single appearance was in a Stanley Cup playoffs game †  The single appearance was during the most recent (2023–24) completed season – some potential to be dropped from this list in near future
