The United Hockey League (UHL) (originally known as the Colonial Hockey League from 1991 to 1997 and last known as the International Hockey League from 2007 to 2010) was a low-level minor professional ice hockey league with teams in the United States and Canada.
The league was headquartered in Rochester, Michigan, and in its last year, consisted of seven teams. It folded in 2010, with most of its teams joining the Central Hockey League (CHL).
The Central Hockey League teams still operating in 2014 were then added to ECHL. The only former UHL/IHL teams still active as of 2017 are the Quad City Mallards, Elmira Jackals, Fort Wayne Komets and Kalamazoo Wings.
