The Flushing–Ridgewood Line, also known as the Corona Avenue Line and previously known as the Fresh Pond Road Line, is a public transit line that operates primarily in Queens, New York City, United States, with its southern terminal on the border with Brooklyn. Originally a streetcar line that began operation in the 1890s, it now consists of the Q58 and Q58 Limited bus routes, operated by the MTA New York City Transit Authority. The Q58 operates between two major bus/subway hubs: the Ridgewood Terminal on the border of Ridgewood, Queens and Bushwick, Brooklyn; and the Flushing – Main Street terminal in Downtown Flushing, Queens. It is among the busiest bus lines in the borough of Queens, with 9.79 million people riding the route in 2014.

The original route of the Flushing–Ridgewood streetcar began at 41st Road and Main Street in Downtown Flushing, just south of the Main Street station of the Long Island Rail Road, and several blocks south of the Main Street subway station on the IRT Flushing Line. It ran south on Lawrence and Rodman Streets, and west on Horace Harding Boulevard to Corona. It then ran generally west along the winding Corona Avenue to Queens Boulevard in Elmhurst, and on Grand Avenue to Maspeth. Between Junction Boulevard in Corona and the intersection of Grand Avenue and Flushing Avenue, the line shared a right-of-way with the Grand Street Line. After a short portion on Flushing Avenue and 61st Street, it ran south down Fresh Pond Road to the Fresh Pond Road station of the BMT Myrtle Avenue Line, where a major trolley barn existed. It then followed the right-of-way of the Myrtle El and former Lutheran Cemetery Surface Line to its own dedicated barn at the Ridgewood Depot, located at Palmetto Street underneath the Myrtle-Wyckoff Avenue station.
