St Mary's Roman Catholic Church, Roman Catholic church in Maryborough, Australia.

St Mary's is a Roman Catholic church in Maryborough featuring a steeply pitched gabled roof and a central stained glass window with tracery. The interior is marked by detailed columns that support pointed arches, creating a vertical emphasis throughout the space.

Maryborough's first permanent Catholic church was designed by Charles Tiffin; its foundation stone was laid on 29 July 1869 and Father Tissot opened it on 4 February 1872, built by G Smith and J Thomas. FDG Stanley extended the nave by three bays and added a large chancel in 1884, recladding the roof in slate. Local architect POE Hawkes designed a further enlargement in 1936.

This church serves as the heart of the local Catholic community, hosting regular services and religious celebrations. The interior with its columns and arches creates a space for both private prayer and communal gatherings.

The church is located at 271-275 Adelaide Street and is easy to find due to its prominent position and heritage status. Visitors should check ahead for service times, as the building is primarily used for worship and religious services.

Father Tissot, the first parish priest, carved the chancel screen and other timber panelling himself and is thought to have helped design the high altar and the carved timber canopy, or baldacchino, above it. Look for this woodwork inside the church he landscaped the grounds around.
