Saint Catherine of Alexandria Church, Tabán, Parish church in Tabán district, Budapest, Hungary.

Saint Catherine of Alexandria Church is a Roman Catholic parish church in the Tabán quarter of Budapest, built in Central European Baroque style between 1728 and 1777. Its nave was added by Christian Obergruber from 1728 to 1736, and Matthäus Nepauer built the Baroque facade and tower from 1750 to 1753. The facade carries statues of Saint Catherine, Saint Andrew and Saint Peter, and a 12th-century tympanum fragment, the "Tabán Christ", is set into the wall of the forecourt.

The church grew from the mosque of Sokollu Mustafa Pasha, converted into a chapel dedicated to Saint Catherine in 1692. A Baroque nave was added between 1728 and 1736 by Christian Obergruber, and Matthäus Nepauer built the facade and tower from 1750 to 1753. The parish was re-established in 1702, and the church was reconstructed several times in the 19th and 20th centuries.

The parish's baptismal register dates from 1692, and marriage and burial records have been kept since 1709. From the mid-18th century sermons were preached in German and Illyrian, and the parish school taught bilingually; most 18th-century friars serving here were Croats. In the forecourt stands the "Tabán Christ", a 12th-century tympanum fragment later built into the church wall.

The church is accessible by public transportation and located in a walkable downtown area. Visitors should note that entry is generally available during service times, so checking opening times in advance is helpful.

In the church's forecourt stands the "Tabán Christ", a 12th-century tympanum fragment later built into the wall of St. Catherine's. Nearby stood Tabán's other church, the Serbian Orthodox St. Demeter's, demolished in 1949 after World War II. The mosque of Sokollu Mustafa Pasha, converted into a chapel in 1692, forms the core of today's building.
