Thomas Finan Lockhart (March 21, 1892 – May 18, 1979) was an American ice hockey administrator, business manager, and events promoter.

He managed operations at Old Madison Square Garden, introduced fans to innovative on-ice promotions which made amateur hockey a profitable event.

[4][5][6] He participated in track and field events with the St. John's Club on 56th Street in Manhattan,[3] and was also interested in boxing,[6] but he never played hockey growing up.

[7][8] He successfully convinced the league to add his three teams to its schedule, with the promise of revenue from ticket sales at Madison Square Gardens.

[7][8] The group also renamed itself to the Eastern Amateur Hockey League (EAHL) with the addition of teams in a fourth state, and elected Lockhart as its president.

[12] He defended criticism of the league's amateur status, by saying that its players earned a primary income outside of hockey, despite receiving money for basic living expenses and recreation.

[10] He also recovered the Hamilton B. Wills Trophy from a pawnbroker, and awarded it for winning a challenge series between teams in Canada and the United States.

[10] In the late 1940s, Lockhart made an interlocking schedule between the EAHL and the Quebec Senior Hockey League, which allowed New York fans to see the all-black line of Herb Carnegie and his brothers play with the Sherbrooke team.

[15] As the league president, Lockhart suspended a player for life in 1952, after Joe Desson assaulted referee Mickey Slowik on the ice.

[9] Lockhart printed souvenir programs without advertisements, but rather inserted of reading material such as columns on the teams and leagues, in hopes that patrons would take it home to share with others.

[20] He also used MAHL players to create improvised all-star teams when a snow storm prevented a National Hockey League (NHL) match.

[21] He also booked figure skating acts Shipstads & Johnson Ice Follies,[19] and Winter Olympics multiple gold medalist Sonja Henie to perform at the Gardens.

[2][27] His roster that season included future NHL referee Bill Chadwick, whom Lockhart later recruited to begin an officiating career.

[34][35][36] In September 1938, Lockhart reached an agreement with W. G. Hardy of the CAHA which regulated international games in North America, set out provisions for transfer of players between the organizations, and recognized of each other's authority.

[39] Lockhart arranged for AHAUS, the CAHA and the International Ice Hockey Federation to hold their annual general meetings concurrently at the New Yorker Hotel in May 1949.
