Grace Church of Kilmarnock, Lancaster County, Virginia, is the largest rural Episcopal church in the Commonwealth.
The original brick building, the town's first church and now a chapel attached to the current church, was consecrated by assistant bishop John Johns in 1852. At that and some other times, Grace Church shared a single rector with historic Christ Church (founded 1670), St. Mary's Church Whitechapel (founded 1669), and/or Trinity Church in Lancaster.
The current sanctuary was dedicated by Bishop Goodwin in 1959, and an arcade connects it with the old church, now a chapel. In 1988, Bishop Peter James Lee consecrated the enlarged Grace House. Further expansion occurred in 2002.
In 2017, the church building was listed on the National Register of Historic Places.
