The National Hockey League (NHL) is a major professional ice hockey league which operates in Canada and the United States. Since its inception in 1917–18, 53 players born within the current borders of the United Kingdom have taken part. None of them, however, were trained within the country. Of these players, 23 are from England, 21 from Scotland, 5 from Northern Ireland and 4 from Wales. Steve Thomas and Owen Nolan played over 1,000 regular season games, while Thomas and Steve Smith are the only ones to have appeared in over 100 playoff games. All three players finished their careers in the 21st century. The only player born in the UK currently playing in the NHL is Nathan Walker of the St. Louis Blues.
