Don Mills Road is a north-south route in Toronto, Ontario, Canada, passing through the former cities of East York and North York. It begins at O'Connor Drive near ramps to the Don Valley Parkway, and ends at John Street in Markham, where it becomes a separate northern section of Leslie Street, which parallels it to the west south of the break. North of Steeles Avenue, the road is designated and signed as York Regional Road 12, which continues along Leslie.
From south to north, it passes through the Toronto neighbourhoods of Todmorden Village, Flemingdon Park, Don Mills, Graydon Hall, Henry Farm, Parkway Forest, Don Valley Village, and north of Steeles Avenue, German Mills in Markham.
Between Sheppard and Finch Avenues, Don Mills Road splits into two one-way curved boulevards named as Don Mills Road East and Don Mills Road West. This section is called The Peanut due to its shape on maps. It surrounds schools, a community centre, and the Peanut Plaza.
