Humber River—Black Creek is a federal electoral district in Toronto, Ontario, Canada, that has been represented in the House of Commons of Canada from 1867 to 1904 and since 1917. Prior to the 2015 election, the riding was known as York West.

The district includes the northwest corner of the former city of North York. It includes the neighbourhoods of Humber Summit, Humbermede, Humberlea, York University Heights, Jane and Finch and the extreme western part of Downsview.

It consists of the part of the City of Toronto bounded on the north by the northern city limit, and on the east, south and west by a line drawn from the city limit south along Keele Street, west along Grandravine Drive, southeast along Black Creek, west along Sheppard Avenue West, south along Jane Street, west along Highway 401, and northwest along the Humber River to the northern city limit.

The riding is represented by Judy Sgro in the Canadian House of Commons.

It was created by the British North America Act which divided the County of York into two ridings: York East and York West.

The West Riding of York consisted of the Townships of Etobicoke, Vaughan and that part of the Township of York lying west of Yonge Street.

In 1874, it was expanded to include all of the Village of Richmond Hill, which had previously been divided between the two York ridings, after the village council had peitioned to have the whole village included in York West.
