Matthew J. Stanbridge was a politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1920 to 1922. Stanbridge was a resident of Winnipeg during his career in politics.
He was elected to the Manitoba legislature in the 1920 provincial election as a Labour Party candidate in the St. Clements constituency. He defeated Liberal incumbent Donald A. Ross byh 127 votes, and sat with the Labour parliamentary group in the legislative opposition for the next two years.
The Labour Party and its allies won eleven seats in the 1920 election, which occurred shortly after the Winnipeg General Strike of 1919. Their support had declined by the time of the 1922 election, and fell to six seats. Stanbridge, running for the Independent Labour Party in St. Clements, finished fourth in a field of four candidates in his bid for re-election.
He attempted to return to the legislature in the 1927 provincial election as a "Farmer-Labour" candidate, but finished a distant third against Progressive cabinet minister Robert Hoey.
