Michael Nicholas Hryhorczuk (November 28, 1905 in Gilbert Plains, Manitoba – July 11, 1978) was a politician in Manitoba, Canada. He served as a member of the Legislative Assembly of Manitoba from 1949 to 1966, and was a cabinet minister in the government of Douglas Campbell. Hryhorczuk was originally a Liberal-Progressive, and later became a Liberal after the party changed its name. His father, Nicholas Hryhorczuk, was also a member of the Legislative Assembly from 1920 to 1945.
Hryhorczuk was educated at the University of Manitoba and the University of Saskatchewan, receiving Bachelor of Arts and law degrees. He worked as a barrister before entering political life, and served as chairman of the Ethelbert School Board and president of the Ethelbert Chamber of Commerce. He also served as reeve of Ethelbert for a time.
He was first elected to the Manitoba legislature in the 1949 provincial election, defeating CCF candidate Fred Zaplitny by over 700 votes in his father's old riding of Ethelbert. He served as a backbench supporter of Campbell's government in the parliament which followed, and was re-elected without difficulty in the 1953 election.
On January 25, 1955, Hryhorczuk was named as the province's Attorney General. He retained this position until the 1958 provincial election, in which Campbell's Liberal-Progressive lost power to Dufferin Roblin's Progressive Conservatives. He formally resigned his position on June 30, 1958.
