Red Deer was a territorial electoral district that was mandated to return a single member to the North-West Legislative Assembly from 1888 until 1902.
The electoral district was named for Red Deer, a community which was incorporated as a village in 1894 and town in 1901.
Red Deer's first representative was physician Robert Brett. There were no official parties in these early assemblies, but Brett aligned himself with the North-West Territories Liberal Party when the Dominion party lines were introduced in 1898.
In the 1891 election, Brett contested the Banff electoral district and Francis Wilkins was acclaimed as the member for Red Deer. In the 1894 election, Wilkins came in third to the elected John A. Simpson and behind Leonard Gaetz. Simpson held the seat in the 1898 election, defeating George Wellington Greene and J. Speakman.
