St. Andrew's is a historic Episcopal church at 247 New Milford Turnpike (United States Route 202), in the Marbledale village of Washington, Litchfield County, Connecticut.

[1] St. Andrew's is located in the rural village of Marbledale, on the south side of New Milford Turnpike at its junction with Wheaton Road.

The largely Loyalist congregation was harassed during the American Revolutionary War, and abandoned its original building, meeting in private homes.

Formed anew in 1791, the congregation rented and then purchased a local Quaker meeting house, which served as its home until 1816.

The only earlier known example of Gothic Revival architecture in Connecticut is the 1814 Trinity Church on the Green in New Haven, designed by Ithiel Town.
