Leland Kitteridge "Hago" Harrington - Born October 13, 1903 in Melrose, Massachusetts – Died July 1, 1959 was a American ice Hockey left winger and coach.

Harrington began his career with the amateur Boston AA Unicorns and the local AAA squad.

In 1925-26 the left winger turned pro with the Boston Bruins, wearing number 15, and scored seven goals for the Bruins playing on a line with Gerry Geran and Herb Mitchell.

The next year he scored 21 times in 32 games for the New Haven Eagles of the Canadian–American Hockey League / Can-Am circuit but was not summoned by the Bruins.

Harrington returned to the NHL for 22 games in the 1927-28 season, and then the Bruins sold Harrington for cash to the Providence Reds and he played eight seasons for the minor pro team.

His best year during this period came in 1931-32 when he led the league with 20 assists while playing for the Providence Reds.

Harrington received one last shot at the NHL after Providence sent him to the Montreal Canadiens for three players, including Armand Mondou. The hard working winger played solidly for his new club and recorded a goal during an opening round playoff loss to the New York Rangers.

Harrington returned to Providence the next season and was a fine playmaker for the club until retiring in 1936. Overall he helped the Reds win the Henri Fontaine Trophy as Can-Am champions in 1930, 1932 and 1934.

After retirement, Harrington became part of the management group of the Boston Garden.

He played in 72 NHL games and scored 9 goals and 3 assists.

Harrington served as the coach of the Boston Olympics from 1940-41 through 1947-48.
