Port Union is a neighbourhood on the eastern border of Toronto, Ontario, Canada. It is bounded by the Rouge River on the east, Port Union Rd. on the west, Lake Ontario to the south, and (nowadays) Highway 401 to the north. The former northern limit to Port Union was Lawrence Ave. The last eastern exit on the highway is located here. Most residents are commuters who travel downtown each day via the 401 or Kingston Road (Highway #2). Average commute times are 40 minutes to 1 hour depending on the level of congestion.

Port Union was part of the Township of Pickering, Ontario until 1984, when municipal reforms in Ontario transferred the neghbourhood to the City of Scarborough. Scarborough was merged with five other municipalities and a regional government to form the new "City of Toronto" in 1998.

The only places of interest of note in Port Union are the eastern edge of the Scarborough Bluffs , Rouge Beach, and the Rouge Hill GO Transit commuter train station.
