Flushing Bay is a tidal embayment in New York City. It is located on the south side of the East River and stretches to the south near the neighborhood of Flushing, Queens. It is bordered on the west by LaGuardia Airport and the Grand Central Parkway, on the south by Northern Boulevard, and on the east by the neighborhood of College Point. The Flushing River empties into the bay at its southeast corner. A 150-foot-wide navigational channel (46 m) dredged at a depth of 14 feet (4.3 m) runs along much of the bay's length.

The East River is a saltwater tidal estuary or strait in New York City. The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island, with the boroughs of Brooklyn and Queens, from Manhattan Island, and from the Bronx on the North American mainland.
