Trinity Episcopal Church (also known as St. John's Parish) is a historic church at 703 West 3rd Avenue (corner of Oak Street) in Pine Bluff, Arkansas. Its congregation meets in a handsome brick Gothic Revival structure, with a square buttressed tower and buttressed side walls with lancet-arched stained glass windows. The church was built 1866-70 for a church congregation organized in 1860 by the Rev. Robert Trimble. Initially named St. John's, it was renamed Trinity after Trimble received guidance from members of the Trinity Church in New York City. It is unique in Arkansas as having a burial chamber under its chancel; it is that of early parishioner Cornelia Bell Roane, who died in 1862. It is an active member of the Episcopal Diocese of Arkansas.
