Milligan Street is a street in Perth, Western Australia that runs from St Georges Terrace to north of Wellington Street. The northern section provides access to the Perth Arena carpark and Telethon Avenue; there are also dedicated Transperth bus roads connecting to the northern end, south of the Fremantle railway line. A small side-street of the same name branches off Milligan Street (on the east side) between Murray and Wellington Streets, and forms a second intersection with Wellington Street.
