St. Cäcilia, Romanesque Revival parish church in the Ostviertel, Regensburg, Germany

St. Cäcilia is a Romanesque Revival basilica of brown brick with light stone trim at Reichsstraße 12 in Regensburg's eastern quarter. Its west tower rises 46 m to a steep red pyramidal roof, with a clock face above three arched openings; the gabled facade has a circular window with three inner circles, three narrow arched windows around a small statue, and five lower arches over three dark entrance arches. A round turret with a conical red roof stands to the right. The church measures 40 m long and 20 m wide.

St. Cäcilia was initiated by Franz Xaver Haberl as a practice church for the Catholic church music school founded in 1887 on nearby Reichsstraße. Friedrich Niedermayer designed it; Bishop Ignatius von Senestrey laid the foundation stone on 16 April 1900, and Dompropst Paul Kagerer blessed it on 5 October 1902. Bishop Anton von Henle consecrated it on 24 March 1913, and the parish was established in 1921.

The church bears the name of Saint Cecilia, patron saint of music, and continues to serve as a place for worship and community gatherings of the Catholic parish. Believers gather here regularly to fulfill their spiritual needs and participate in shared religious experiences.

St. Cäcilia stands at Reichsstraße 12 in Regensburg's Ostviertel, near the Hochschule für katholische Kirchenmusik. The church is oriented to the south, with the 46 m tower at the west end and a free staircase of exposed brick leading up to the entrances. The nave measures 40 m by 20 m; the second organ console in the choir area reflects its use for church music.

The five bells are tuned to the notes above the name "Caecilia" in the vesper antiphon, c′–d′–e′–g′–a′. Bells 1, 2 and 5 were cast in 1901 by Lothar Spannagl in Regensburg; bells 3 and 4 followed in 1949 from Hamm in Frankenthal. The first organ, Steinmeyer opus 720 of 1901 with 31 stops, was financed by donations of pipes and stops and installed before the church was finished.
