St. John's Protestant Episcopal Church is a historic Episcopalchurch at One Hudson Street in the Getty Square neighborhood of Yonkers, Westchester County, New York. The complex includes the church, chapel, rectory, parish house, and school. The church was originally constructed in 1752, with an addition in 1849, and modifications to the front facade in 1874 by noted architect Edward Tuckerman Potter (1831–1904). It is constructed of rough gray fieldstone with red brick on the corners. It is cruciform in plan, three bays wide, with a slate-covered gable roof. The front facade features a rose window and four battered buttresses. The parish house and chapel were constructed in 1890–1891 and are connected to the church. The 21⁄2-story, five-bay-wide rectory was also constructed in 1890–1891 and is connected to the chapel. The additions made during 1890–1891 were by noted architect Robert Henderson Robertson (1849–1919).
