St. Bonifatius, Catholic church in Bad Nauheim, Germany.

St. Bonifatius is a neo-Gothic church in Bad Nauheim with a nave ending in a choir with a sixteenth-sided apse, and a tower attached to the north side of the nave. Its octagonal top storey, with tracery sound arches, houses five bells beneath an eight-sided spire. The central nave and south aisle form a hall church, while the north aisle gives a basilica section. The organ, built in 1996 by Gebr. Link, has 34 registers, two manuals and a pedal.

The church was built in the late 1800s to serve the growing number of Catholic spa visitors coming to Bad Nauheim. It was officially dedicated on 8 June 1905, marking the completion of the construction project.

The entrance features a sculptural representation of Saint Bonifatius created by Anton Mormann, reflecting the religious identity of the building. This artwork shows how the saint is honored within the local Catholic community.

The church is located at Zanderstraße 13 and serves as the parish church for the local Catholic community. Visitors can find regular services held there and can inquire about visiting information at the parish office.

The 1996 organ by Gebr. Link of Giengen has 34 registers on two manuals and a pedal, with couplers II/I, I/P and II/P. The church also holds five bells in the tower's octagonal belfry, hung behind tracery-decorated sound arcades.
