The Q17 bus route constitutes a public transit line in Queens, New York City, running primarily along Kissena Boulevard, the Long Island Expressway service road (Horace Harding Expressway) and 188th Street between two major bus-subway hubs in the neighborhoods of Jamaica and Flushing.

The route continues north on 188th Street through Jamaica Estates and Utopia to the Long Island Expressway (LIE) at the Fresh Meadows shopping center.

[4] During weekday midday hours and weekday rush hours in the peak direction (AM to Flushing; PM to Jamaica), alternate southbound local service terminates at 188th Street and Horace Harding Expressway in Fresh Meadows.

During weekday rush hours, bi-directional limited-stop service is operated along the full route between Jamaica and Flushing.

The original Q17 route ran along Homelawn Street, Utopia Parkway, and Fresh Meadow Lane between Hillside Avenue and Horace Harding, passing by St. John's University.

[11] In 1931, the New York City Board of Estimate was deciding which bus route franchises would be given to which private operators.

[15] On July 1, 1939, the Q17 became interlined with the Q20, meaning that north of Flushing the bus would continue via the Q20 route to College Point.

[20] Beginning on June 8, 1942, due to restrictions on gasoline and tire usage during World War II, the service was truncated to 14th Avenue and 122nd Street in College Point.

[8][26][27][28] On December 19, 1960, the Flushing Heights Civic and Improvement Association requested that the NYCTA restore the former Q17-20 service.

[32] Limited-stop service was estimated to save riders traveling longer distances five minutes, and was provided by alternate Q17 trips.

[47] On January 29, 2025, the current plan was approved by the MTA Board, and the Queens Bus Redesign will go into effect by Labor Day.
