# Hamilton Centre (provincial electoral district)

Hamilton Centre is a provincial electoral district in Ontario, Canada, that is represented in the Legislative Assembly of Ontario.
It was created for the 1926 provincial election but abolished with the 1999 provincial election when the number of constituencies represented in the legislature was reduced. It was re-created for the 2007 election from parts of Hamilton East, Hamilton West ridings. It consists of the part of the City of Hamilton bounded by a line drawn south from the city limit along Kenilworth Avenue, west along the Niagara Escarpment, northeast along Highway No. 403, east along the Desjardins Canal to Hamilton Harbour.
