Dreikönigskirche, Lutheran church in Sachsenhausen, Frankfurt, Germany.

Dreikönigskirche is a neo-Gothic hall church of red Main sandstone, built 1875–1880 to Franz Josef Denzinger's design. Its single west tower, 80 m high, rises through two square storeys to an octagon with a pointed spire, echoing the cathedral across the river. Inside, five nave bays run to a 5/8 polygonal choir, with sandstone galleries on compressed basket arches and tracery balustrades.

Construction took place between 1875 and 1880 under architect Franz Josef Denzinger, replacing an older chapel from 1340. The new church was built to serve the growing Protestant community in this area.

The Three Kings were chosen as patrons because they were the protectors of travellers, fitting a town on the Main trade road. From 1945 to 1957 Kurt Thomas was church musician and founded the choir that became the Frankfurter Kantorei; Helmut Walcha was organist from 1946 to 1981. Cantata services and concerts continue, and in 1978 the church hosted the premiere of Kurt Hessenberg's St Luke Passion under Helmuth Rilling.

The main portal in the west tower opens onto a small square set back from the Sachsenhausen Main riverbank, opposite the cathedral tower. The nave seats 840 people across five bays, with three front bays flanked by sandstone galleries. The church is a listed monument and largely retains its neo-Gothic interior apart from the windows and organ.

The 1961 organ by Karl Schuke of Berlin has 47 stops on three manuals and pedal, and its disposition was drawn up by organist Helmut Walcha, who played here from 1946 to 1981. The city of Frankfurt gave the instrument to honour him.
