St. Johannes der Täufer, Roman Catholic parish church in Oberviechtach, Upper Palatinate, Germany

St. Johannes der Täufer is a church building in Oberviechtach, Bavaria, combining multiple architectural periods within its structure. A gothic choir and stone tower coexist with baroque elements from the late 1700s and a modern octagonal addition built between 1963 and 1965.

The Gothic choir and the choir flank tower in ashlar masonry on its north wall survived a town fire, after which the nave was rebuilt in Baroque style in 1775/76. In 1963–65 an octagonal extension was added to the west. The church is listed as a Bavarian monument under number D-3-76-151-13 and belongs to the Diocese of Regensburg.

The parish belongs to the Diocese of Regensburg and is dedicated to John the Baptist. Its high altar was made by artists from Amberg, and the 1797 organ case by Andreas Weiss was kept when a new Eisenbarth organ of 32 stops on two manuals and pedal was installed in 2012.

The church stands in the town centre of Oberviechtach, in the Upper Palatinate district of Schwandorf, and is listed as a Bavarian monument under the number D-3-76-151-13. The nave holds three axes under a groin vault, and the west end is formed by the octagonal addition of 1963–65, which marks the entrance side for visitors coming from the town.

The 2012 organ by Orgelbau Eisenbarth has 32 stops on two manuals and pedal. Behind the 1797 case by Andreas Weiss, a rear extension was added to house the new instrument, so the historic front and the modern works stand as separate parts.
