Calvary Church is an Episcopal church located at 273 Park Avenue South on the corner of East 21st Street in the Gramercy Park neighborhood of Manhattan, New York City, on the border of the Flatiron District. The church complex is located within the Gramercy Park Historic District and Extension.
The Calvary Church parish was founded in 1832, and initially used a wooden-frame church on what was then Fourth Avenue – which has since become Park Avenue – uptown of its current site. That building was moved to the current location in 1842, and the new Gothic Revival sanctuary, designed by James Renwick, was completed in 1848.
