Morrison Mann MacBride (August 20, 1877 — June 5, 1938) was an Ontario merchant and political figure. He represented Brant South in the Legislative Assembly of Ontario from 1919 to 1926 as a Labour member and then Brantford from 1934 to 1938 as an Independent and then Independent Liberal member.
MacBride broke with the United Farmers of Ontario-Independent Labour Party coalition that took power following the election after the Labour contingent voted to nominate Walter Rollo rather than MacBride for the position of Minister of Labour. MacBride, however, argued that his departure from the caucus was due to its acquiescence to the United Farmers in the selection of cabinet members. MacBride remained a Labour MLA but sat in the Opposition benches and ran for re-election as a Conservative-Labour candidate in 1923. After his second term in the legislature ended in 1926 he did not run for re-election and was appointed Supervisor of Highways by the Conservative provincial government of Howard Ferguson before returning to the legislature in the 1934 provincial election.
He was born in Renfrew County, Ontario and educated in Arnprior. He learned the printing trade and came to Brantford to play with a lacrosse team there, also setting up a printing company. MacBride served as mayor of Brantford from 1918 to 1920, in 1925, from 1933 to 1934 and from 1936 to 1937. He served as Minister of Labour in the provincial cabinet from 1937 to 1938. He died while still in office in Brantford in 1938.
