Rosenkranzkirche, Catholic parish church in Bad Neuenahr, Germany

The Rosenkranzkirche is a Romanesque Revival parish church on Telegrafenstraße in Bad Neuenahr, built 1899–1901 to designs by August Menken and consecrated in 1904. Its 60-metre tower rises on the east side of the nave, and a 1955 tympanum by Ernst Matschulla above the main portal shows the Coronation of Mary by the Trinity. Inside, pointed-arch window openings cut into smooth walls, a Rhineland alternating pier system, and a star vault over the square crossing.

The Rosenkranzkirche was built from 1899 to 1901 to designs by August Menken and consecrated in 1904, though it was only completed in 1907. Donations funded a thorough interior renovation in 2009. The July 2021 flood caused severe damage, especially subsidence. In Advent 2021, artist Rafael Buttlies lit the church windows in various colours under the motto "Hoffnung des Lichtes für das Ahrtal".

The church is dedicated to Mary, Queen of the Most Holy Rosary, and belongs to the Rosenkranzpfarrei parish community of St. Marien and St. Willibrord in the Diocese of Trier. In the chapel circle, the first chapel holds a 17th-century wooden Madonna from the former Josefskapelle, while the fifth, set up in 2009 as a peace chapel, displays small wooden crosses with the names of fallen parish members.

The church is easy to reach on foot in the town center, with several bus stops and parking areas nearby. Visiting during daytime is recommended since natural light illuminates the interior details and decorations.

The monumental fresco on the right transept wall depicts the 1571 Battle of Lepanto, whose outcome was credited to Mary's help and the rosary prayer ordered by Pius V. The church's dedication as Maria Rosenkranzkönigin follows the same theme.
