St. Johannes Baptist, Gothic parish church in Nabburg, Germany.

St. Johannes Baptist is a Gothic basilica in Nabburg, built from east to west with a short three-aisled nave, a transept and two polygonal choirs, one at each end. The surviving south tower rises in six storeys to an octagonal lantern and spire; the north tower collapsed in 1536 and was never rebuilt. Much of the exterior is plastered, while the transept walls, buttresses and window tracery show bare stone.

Construction of the present church probably began before 1300 under the influence of Regensburg Cathedral and was likely completed around 1359. The north tower collapsed in 1536 and was never rebuilt, taking parts of the north aisle with it. In 1576 iconoclasm during the Reformation destroyed numerous works of art.

The neo-Gothic furnishings installed in 1898 replaced the Baroque interior and were removed after the Second Vatican Council, then reinstalled and restored between 1978 and 1981. They include the high altar of 1868, a winged altarpiece with carved reliefs of the Annunciation, the Adoration of the Magi, John the Baptist's preaching and Christ's baptism. The choir and transept windows, donated in 1900 and 1904, were designed by Franz Xaver Zettler of Munich.

The church sits centrally on Kirchplatz and is easy to find thanks to its distinctive southern tower. This tower serves as a landmark for visitors navigating the square and the surrounding area.

The organ was built in 1979 by Guido Nenninger and features 31 stops spread across three manuals and a pedal system. This late 20th-century instrument represents a modern addition to the Gothic architecture.
