William Robinson (November 5, 1823 – July 21, 1912) was an Ontario businessman and political figure.

He elected as an independent was a notable historic occasion in Ontario's history.

He negotiated with the legislature on behalf of the Kingston and Pembroke Railway and secured a $121,000.00 bond toward the building of it.

Robinson was a Justice of Peace for over forty years, but when the Tories were brought into Toronto in 1905 they relieved him from the post.

Robinson once said that he had only cast one Tory vote in his life, and that was when two conservatives were running in Frontenac County.
