Sherbrooke Township is a township in Steele County in the U.S. state of North Dakota. Its population as of the 2000 Census was 62, which had dropped to an estimated 46 people as of 2009. The township shares its name with Sherbrooke, North Dakota, which was the county seat from 1885 to 1919.
Sherbrooke Township was organized in 1885 from survey township 146N, Range 55W. The first settlers were principally of Norwegian, Canadian, and American ancestry. Though the township was not on a major rail line, the promise of future rail service led to a growth in population with a high of 303 people in 1910. However, rail service never materialized, and in 1919 voters in Steele County decided to move the county seat to Finley, which was closer to the railroad. Losing the county seat eventually led to Sherbrooke township's gradual decline.
