Holy Trinity Anglican Church is a heritage-listed Anglican church precinct, containing the church, rectory and adjacent cemetery, at 71-85 Gilmour Street, Kelso, Bathurst Region, New South Wales, Australia. The church was built from 1833 to 1878, with John Foster being responsible for the building of the original church. Edmund Blacket designed the rectory. The property is owned by Anglican Property Trust Diocese of Bathurst and Parish of Kelso, Anglican Diocese of Bathurst. It was added to the New South Wales State Heritage Register on 14 January 2011.
The Pioneer Cemetery comprises the oldest part of the cemetery which is located closest to the church building. Originally established in 1826, the cemetery has been extended considerably to the north in distinct sections. The cemetery is not a public cemetery and is managed by a cemetery trust with fees charged and a cemetery fund established. Its constant care and maintenance has been a considerable task relying heavily on the gift of volunteer labour from men and women of the congregation.
