Trinity Episcopal Church is a historic Episcopal church located at 1108 N. Adams Street in Wilmington, New Castle County, Delaware. It was designed by architect Theophilus P. Chandler, and built in 1890. It is constructed of grayish white "Avondale" limestone laid in random coursed rock-faced ashlar blocks in the Gothic Revival style. It features pointed arch windows and doors, a high spire, the additional pinnacles on the side of the building, and buttresses. The parish house and rectory were added to the church in 1911 and the chapel was added in 1949. An adjacent brick three story rowhouse, known as Harris House, is attached to the complex by a second story walkway.
