Bay Parkway is a 2.7-mile-long (7.82 km) boulevard in the west portion of the New York City borough of Brooklyn.

Bay Parkway begins at Ocean Parkway and continues for approximately 3 miles (4.8 km) southwesterly to Bath Beach, past Seth Low Playground and Bealin Square[2] toward Bensonhurst Park,[3] Shore Parkway (Exit 5), and Ceasar's Bay shopping plaza on Gravesend Bay.

Along Bay Parkway are many Chinese, Russian and Italian-American businesses and many residential buildings and co-ops.

Bay Parkway was known as 22nd Avenue until the 1930s, when the name was changed to facilitate large-scale apartment-type residential development.
