St. Andrew's Episcopal Chapel is an historic Episcopal chapel located at Sudlersville, Queen Anne's County, Maryland, built as a chapel of ease for St. Luke's Church in Church Hill. It was listed on the National Register of Historic Places in 1984. A small Carpenter Gothic-style board-and-batten structure constructed in 1878, it divided into two principal parts: a large rectangular sanctuary three bays long and two bays wide with a steeply pitched gable roof, and a slightly smaller but similarly proportioned chancel, two bays long and one bay wide. The entry features a wide Gothic-arched double doorway with a steep gable roof. The sanctuary has a pair of stained glass lancet windows on the first floor, and a circular stained glass rose window in the upper gable.
