Don Mills was a provincial electoral district in Ontario, Canada. It was created for the 1963 provincial election, and lasted until the provincial redistribution on 1996. The riding was formally retired with the 1999 provincial election. At its abolishment, the riding consisted of the neighbourhoods of Woodbine Gardens and Parkview Hill in the borough of East York plus the neighbourhoods of Flemingdon Park and the southern part of Don Mills in North York (all of North York south of Lawrence Avenue). It was abolished into Don Valley East, Don Valley West and Beaches—East York

The riding was a bastion of strength for the Progressive Conservative Party of Ontario for most of its history, and was represented by moderate Tory cabinet ministers Dennis Timbrell and David Johnson at different times. The Liberal Party and the New Democratic Party both represented the riding between 1987 and 1993.
