St. Kilian Schweinfurt, Parish church and architectural monument in Schweinfurt, Germany.

St. Kilian is a Roman Catholic parish church in Schweinfurt, rebuilt from 1952 to 1953 by Würzburg cathedral architect Hans Schädel as a flat-roofed hall church in the tradition of the Weimar Bauhaus. Its trapezoidal plan narrows toward the east choir, and the north tower, with walls from the predecessor church, also carries a flat roof. The 250-square-metre choir window, made in 1953 by Georg Meistermann, is titled "Aussendung des Heiligen Geistes" and is considered one of Germany's largest church windows.

A first church on this site, consecrated in 1927, was a neo-baroque hall church by Peter Krammer with a bulbous tower. Bombing in World War II destroyed the nave and south wall while the tower largely survived; US troops held a memorial service at the ruin in April 1945. From 1952 Hans Schädel rebuilt the church using the surviving walls, and Bishop Julius Döpfner consecrated it on 20 September 1953.

The church is named after Saint Kilian, an Irish missionary killed in Würzburg in 689. Since 2018 the choir has housed the "krosskirche", a youth church run by the BDKJ and the diocesan youth ministry, with new seating, altar and technology. The bronze bells of the 1927 church still ring with a "Salve Regina" motif.

The main portals sit on the west side beneath the organ gallery, while the choir faces east and the tower stands on the north side. A projecting entrance section with a scalloped canopy and short columns marks the approach; steps lead up to it. The south aisle wall carries an attached arcade.

The 250-square-metre choir window, made by Georg Meistermann in 1953, is considered one of Germany's largest church windows. Apart from twelve fish, it is abstract and titled "Aussendung des Heiligen Geistes" (Sending of the Holy Spirit).
