Sheppard Avenue is an east–west principal arterial road in Toronto, Ontario, Canada. The street has two distinct branches near its eastern end, with the original route being a collector road leading to Pickering via a turnoff, and the main route following a later-built roadway which runs south to Kingston Road. To avoid name duplication, the Toronto portion of the northern branch was renamed Twyn Rivers Drive. The section of the street entirely in Toronto is 34.2 kilometres in length, while the Pickering section and Twyn Rivers Dr. is 5.4 kilometres long.
