Nicholas Apoluner Hryhorczuk (December 17, 1888 – November 23, 1979) was a politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1920 to 1936, and again from 1941 to 1945. Hryhorczuk married Nelly Dzaman in 1905. From 1917 to 1919, he served as reeve of Ethelbert municipality. Hryhorczuk was a member of the Canadian Foresters.
Hryhorczuk was first elected to the Manitoba legislature in the 1920 provincial election. Running as an "Independent Farmer", he was easily elected in the Ethelbert constituency. In the 1922 election, he was nominated as a candidate of the United Farmers of Manitoba (UFM) and was re-elected without opposition in a deferred election.
The UFM won the 1922 election, and formed government as the Progressive Party of Manitoba. Hyrhorczuk rallied support for John Bracken to serve as Premier of Manitoba, and later became a backbench supporter of Bracken's government. He was re-elected in the provincial elections of 1927 and 1932.
