The 1910 NHA season was the first season of the National Hockey Association men's professional ice hockey league. The season started on January 5, but was suspended immediately and the league then absorbed the Ottawa and Shamrocks teams of the Canadian Hockey Association and the season continued from January 15 to March 15. Seven teams played 12 games each. The Ottawa Hockey Club played two Stanley Cup challenges during the season, but lost the Cup to their rivals the Montreal Wanderers who won the league championship and played a Cup challenge afterwards.
