Washington Cemetery is a historical and predominantly Jewish burial ground located at 5400 Bay Parkway in Mapleton, Brooklyn, New York, United States.

This part of Kings County was not yet incorporated into the City of Brooklyn, and the legislation resulted in the development of several large parcels of farmland as cemeteries.

Bennet was born in New York, and was proprietor and principal of the Arlington House, an educational institution on Long Island.

The interior of Cemetery #1 is crisscrossed by paths called Rose, Hyacinth, Jasmine, Aster, Lotus, and Evergreen avenues.

It has "burial society" sections established by early immigrant groups of landsmannschaft or synagogue congregations.

In December 2010, this section sustained the majority of some 200 overturned and broken headstones damaged by vandals at the cemetery.

It is triangular, bounded on two of its sides by major thoroughfares: McDonald Avenue on the northeast and Bay Parkway on the northwest; it has four entrances and exits.
