Reuben White (c. 1779 – January 6, 1858) was a farmer, businessman and political figure in Upper Canada.
He was likely born in Schoharie County, New York, in 1779, the son of William White and Hannah Tompkins.
The family moved to Upper Canada and settled in Sidney Township, Hastings County, Ontario about 1800.
Following the 1837 Rebellion he was arrested in December of that year on a charge of insurrection or treason but released in early January and the trial never occurred.
He is buried in White’s Cemetery, near his farm, and has a tall column headstone demonstrating his prominence in the community.
