St Mark's Anglican Church, Warwick, Anglican church in Warwick, Australia.

St Mark's Anglican Church is a coursed sandstone building at the corner of Grafton and Albion Streets, laid out on a traditional cruciform plan with a tower abutting the western end of the nave. Its stone came from the Sidling Quarries, and window reveals, tracery and buttress facings are of smooth-faced sandstone. A projecting entrance porch with three pointed arches and gabled pinnacles faces a driveway off Grafton Street.

The first Anglican service in Warwick was held around 1848; a timber church with nave and transepts was built on this Grafton Street site in 1858 by John Niblock and John Thompson for £329/10/0. Benjamin Glennie, rector from 1860, pushed for a permanent building: architect Richard George Suter designed it, John McCulloch built it, and Bishop Edward Tuffnell laid the foundation stone on 19 March 1868 using stone from his Sidling Quarries. Additions followed in 1874, and in 1938–39 Lange Leopold Powell's alterations added gabled structures flanking the chancel, extended the nave and began the west tower.

The name follows Benjamin Glennie's plan to dedicate four Darling Downs churches to the four apostles, with Warwick receiving Mark. The first Anglican service in Warwick was held about 1848 in the old Court House in Alice Street. The 1938 alterations added Queensland's first columbarium wall, and the 1962 tower extension was faced with concrete scoured to resemble stone.

The church stands at the corner of Grafton and Albion Streets, but entry is from the western side, up a driveway off Grafton Street rather than from the street frontage. A projecting porch reached by three concrete steps forms the entrance, so step-free access is not available there. The tower abuts this western end beside the entrance.

The 1938-1939 alterations by architect Lange Leopold Powell added Queensland's first columbarium wall, and the tower base begun then was extended in 1962 with concrete scoured to resemble the church's stonework. Powell died before the work finished, so Dods and Thorpe Architects of Brisbane supervised its completion.
