Spirit River was a provincial electoral district in Alberta, Canada. It was mandated to return a single member to the Legislative Assembly of Alberta from 1930 to 1993.
Spirit River was created out of the northern half of the Grande Prairie district for the 1940 election. It contained the towns of Spirit River and Rycroft, and the Peace River formed its northern boundary. It saw no major boundary changes until it was replaced by Spirit River-Fairview, Grande Prairie and Smoky River in 1971.
In the 1940 election, Spirit River was picked up by Social Credit candidate Henry DeBolt (for whom the community DeBolt was named). This is despite the fact that the incumbent Social Credit MLA for the area, William Sharpe, was defeated in what remained of the Grande Prairie district by an independent challenger. DeBolt served as MLA for twelve years, but lost the Social Credit nomination for the 1952 election to Adolph Fimrite. He attempted to defend his seat as an independent candidate, but finished last in a field of four candidates.
Fimrite, who won on the second count in 1952, defended the seat until it was abolished in 1971. The last election in this district saw a surge in support for the New Democrats, foreshadowing party leader Grant Notley's 1971 victory over Fimrite in Spirit River-Fairview, which absorbed most of Spirit River.
