York Centre is a provincial electoral district in Ontario, Canada, that has been the name of ridings in the Legislative Assembly of Ontario three different times. It was created initially in 1955 from the southern part of York North. It was dissolved in 1963 when it was split into three ridings called Yorkview, Downsview and Armourdale. In 1967, it was reconstituted north of Steeles in the township of Markham. This lasted until 1999 when it was dissolved into Markham—Unionville. The name was given to a new riding formed in its original location south of Steeles. It remains as an existing riding today.
