Line 1 Yonge–University is the oldest and busiest line of the Toronto subway in Toronto, Ontario, Canada. It is operated by the Toronto Transit Commission, has 32 stations and is 30.2 km (18.8 mi) in length. It opened as the Yonge subway in 1954 as Canada's first underground passenger rail line. Various extensions were completed between 1963 and 1996. Averaging nearly 732,000 riders per weekday, the Yonge–University line is the second busiest rapid transit line in North America, after the IRT Lexington Avenue Line of the New York City Subway.

The Yonge portion of the line runs under Yonge Street from its northeastern terminus at Finch Avenue to Union Station, connecting with Line 4 Sheppard at Sheppard–Yonge and Line 2 Bloor–Danforth at Bloor–Yonge. It continues along University Avenue to St. George and Spadina, which both connect to Line 2. It runs for two stations along Spadina Avenue before continuing along the Cedarvale and Nordheimer ravines to Allen Road. Its northwestern terminus, Downsview, is located at the intersection between Sheppard Avenue and Allen Road.

The line's name has been changed as it was extended. Following its opening in 1954, it was called "the subway" (Yonge subway is its retronym). In 1963, it was extended along University Avenue to St. George station and renamed the "Yonge–University Line". Briefly in 1966, the Yonge–University subway ran in two branches: one west along Bloor to Keele (Yonge–University–Bloor), the other east along Bloor and Danforth to Woodbine (Yonge–University–Danforth) via Bay Lower station.
