Vaughan—King—Aurora was a federal electoral riding in Ontario, Canada, that was represented in the House of Commons of Canada from 1997 to 2004, and was a provincial electoral riding represented in the Legislative Assembly of Ontario from 1999 to 2007.

It was abolished in 2004, as ridings in York Region were redistributed due to its fast-growing population.

The provincial riding of Vaughan—King—Aurora was created before the 1999 election when Ontario provincial electoral districts were redefined to be the same as the federal districts.

The riding was last held by Greg Sorbara, representing the Ontario Liberal Party in the Legislative Assembly of Ontario.

Sorbara served as the Minister of Finance for the Cabinet of Ontario from 2003 to 2005, and from 2006 to 2007.
