Union is a subway station on Line 1 Yonge–University of the rapid transit system in Toronto, Ontario, Canada. It opened in 1954 as one of twelve original stations on the first phase of the Yonge line, the first rapid transit line in Canada. It was the southern terminus of the line until the opening of the University line in 1963.

Union Station is located on Front Street between the Yonge Street and University Avenue sections of the line. It is named for and directly connects to the railway station and regional bus terminal of the same name, serving all GO Transit train lines and train-bus services as well as Via Rail intercity routes (including Amtrak's Maple Leaf service to New York City). It also connects to the Union Pearson Express, a rail link to Toronto Pearson International Airport. It is the only station on Line 1 with a direct connection to GO Train and Via services.

Based on Toronto's street grid, Union is the southernmost subway station and the closest to Lake Ontario; however, using standard compass directions, Kipling and Islington Stations are further south. It serves approximately 100,000 people a day, ranking it as the fourth-busiest station in the system, after Bloor-Yonge, St. George & Sheppard–Yonge, and the busiest served by only one line. Adjacent to the subway station is an underground terminal loop for two streetcar routes, the 509 Harbourfront and 510 Spadina.
