The County of Victoria, or Victoria County, was a county in the Canadian province of Ontario. It was formed in 1854 as The United Counties of Peterborough and Victoria, and separated from Peterborough in 1863. In 2001, the county was dissolved and reformed as the City of Kawartha Lakes. Though first opened to settlement in 1821, the area that was encompassed by Victoria County has a history of Indian occupation, first by the Hurons.
