St. Peter's Episcopal Church of Peekskill, New York, United States, is located on the north edge of the city's downtown.

The church property is located at the southeast corner of the intersection of Howard and North Division streets, just outside the boundary of the Peekskill Downtown Historic District.

[1] Inside, the nave follows a traditional linear plan with a central aisle between wooden pews.

It is a two-story, three-bay Greek Revival house sided in brick laid in Flemish bond trimmed in cast iron.

Inside it retains much of the original plaster finishing and decoration, including eared door and window surrounds.

[1] Behind it along Howard Street, at the northeast corner of the property, is the Frost Memorial Parish House, a two-story Tudorbethan five-bay–long hall with stucco walls and half-timbers.

Its roof, gabled with a half-hip at the south and gable-on-hip at the north (front) end, is shingled in slate.

The main entrance at the north end is a two-story symmetrical projecting bay with raised parapet.

In 1838 Ward Howard, a resident of what was then the village of Peekskill, offered the church land behind the house he had built a few years earlier.

The younger Upjohn's design recalled the simple Gothic English country parish churches that Upjohn and other architects of the mid-century had advocated and built for Episcopal congregations in the Northeast and elsewhere, under the influence of Ecclesiogical movement in church architecture[2] Unlike other neo-Gothic government and institutional buildings of the late Victorian era, decoration is minimal.
