St John's Anglican Church, Dalby, Anglican church building in Dalby, Australia

St John's Anglican Church is a brick church at 153 Cunningham Street in Dalby, built in 1922–1923 to a design by Harry Marks. It is the third church of that name on the site, replacing a timber church of 1876 that was moved and altered to serve as a parish hall. Its foundations are reinforced concrete built on arches, sunk to a bed of solid yellow clay 8 feet (2.4 m) down.

The present building was constructed between 1922 and 1923, replacing a timber structure from 1876 that had become unsafe. The new construction was engineered with special foundations on solid ground to avoid the structural problems that had affected earlier versions.

Two stained-glass windows from the 1876 timber church were moved into the 1922 building. The St Cecilia window in the baptistery was given in 1901 in memory of Mrs Geizel, and the Mulholland Memorial window, showing the Transfiguration, now stands at the east end. Both were designed by Sydney churchman E. A. Milford.

The church stands at 153 Cunningham Street, on the block granted in 1859 at the corner of Cunningham and Drayton streets. The 1922 building contract went to J and F Muller of Toowoomba at an estimated cost of £4123. The site was excavated to a depth of 8 feet (2.4 m) to reach a bed of solid yellow clay for the reinforced concrete foundations.

Architect Henry James Marks designed reinforced concrete foundations laid on solid yellow clay to prevent structural problems that had affected earlier buildings. This engineering choice made the church more resistant to local ground conditions.
