St. Andrews is an historical provincial electoral division in Manitoba, Canada. It existed on two separate occasions, and was located to the immediate north of Winnipeg, the capital city.

When Manitoba joined Canadian Confederation in 1870, the St. Andrews region of the province was given two seats: St. Andrews North and St. Andrews South. It was consolidated into a single constituency following redistribution in 1879. In 1899, it was merged with the Kildonan constituency and Kildonan and St. Andrews.

The St. Andrews electoral division was initially dominated by anglophone "old settlers", who had resided in the Red River territory before it was incorporated as a province. Many of the old settlers were known as "mixed-bloods", referring to persons of British and aboriginal descent (the term was not considered offensive at the time). John Norquay, a "mixed-blood" leader who served as Premier of Manitoba from 1878 to 1887, represented St. Andrews in the provincial legislature for many years. Alfred Boyd, who is sometimes lists as Manitoba's first premier, also represented a St. Andrews constituency from 1870 to 1874.
