St. Mariä Himmelfahrt, Roman Catholic church in Hamminkeln, Germany.

St. Mariä Himmelfahrt is the Catholic parish church of Hamminkeln, built in brick in the Neo-Gothic style to plans by royal government master builder Hilger Hertel. It is a two-aisled hall church with cross-ribbed vaulting carried on columns, a recessed polygonal choir and a side tower topped by an eight-sided pyramidal roof. A gable set forward like a transept articulates the exterior.

Hamminkeln became Protestant in 1612, and its parish church, the so-called White Church, served that congregation. A Catholic community was founded only in the late 19th century, after a private donor gave land and building capital. The Neo-Gothic brick church, known as the Red Church, was consecrated on 4 July 1895 by Münster bishop Hermann Jakob Dingelstad.

The dedication to the Assumption of Mary shows the strong Catholic roots of the Hamminkeln community and its connection to the Diocese of Münster. The church serves as a gathering place where people come together regularly to practice and share their religious traditions.

The church is located in Hamminkeln and can be easily reached on foot with clear paths leading to the entrance. Visitors can view the building from outside and attend regular religious services held throughout the year.

The church is nicknamed the "Rote Kirche" (Red Church) for its brick construction, distinguishing it from Hamminkeln's older "Weiße Kirche", which became Protestant in 1612. The choir windows were made by the Düsseldorf workshop Hertel & Lersch and show the Annunciation, the Visitation and the Coronation of Mary.
