The sidewalk clock on Jamaica Avenue is an early-20th-century sidewalk clock at the southwest corner of Jamaica Avenue and Union Hall Street in the Jamaica neighborhood of Queens in New York City. The cast iron clock's design incorporates a bell-cast shaped column base and an anthemion finial above the dial casing. The clock originally was installed at 161-11 Jamaica Avenue but was moved in 1989 to 92-00a Union Hall Street. The clock is a New York City designated landmark and was listed on the National Register of Historic Places in 1985.
