St. Bonifatius in Wiesbaden, Germany, is the central Catholic parish and church in the capital of Hesse. The present building was designed by architect Philipp Hoffmann in Gothic Revival style and built from 1844 to 1849. Its twin steeples of 68 m (223 ft.) dominate the Luisenplatz. The parish is part of the Diocese of Limburg.

Wiesbaden is the capital of the German state of Hesse, and the second-largest Hessian city after Frankfurt am Main. With around 283,000 inhabitants, it is Germany's 24th-largest city. Wiesbaden forms a conurbation with a population of around 500,000 with the neighbouring city of Mainz. This conurbation is in turn embedded in the Rhine-Main Metropolitan Region—Germany's second-largest metropolitan region after Rhine-Ruhr—which also includes the nearby cities of Frankfurt am Main, Darmstadt, Offenbach am Main, and Hanau, and has a combined population exceeding 5.8 million.
