Église Sainte-Madeleine de Châteaudun, Medieval church in central Châteaudun, France

The Église Sainte-Madeleine de Châteaudun is a Catholic abbey church in Châteaudun, Eure-et-Loir, built over the 12th, 13th and 16th centuries. Its walls are weathered light tan stone under a steep grey slate roof, with a tower on the left capped by a dark pyramidal spire. A row of triangular gables, each above a round-arched window, runs along the upper wall, and three round-arched doorways open at ground level.

The former abbey church of the Madeleine was built in stages across the 12th, 13th and 16th centuries. In 1152 Gosselin de Lèves, bishop of Chartres, confirmed that the church of Saint-Pierre de Lanneray was attached to the abbey. The abbey was placed in commendam in 1546, and in 1634, under abbot Jacques de la Ferté, the Génovéfain reform was introduced. It was listed as a monument historique on 25 July 1922.

The Madeleine was a parish as well as an abbey: its parish register survives, recording baptisms from 1478 to 1486 and marriages from 1490 to 1494. The abbey was placed in commendation in 1546, and in 1634, under abbot Jacques de la Ferté, the Génovéfain reform was introduced. The church now belongs to the Saint-Aventin parish of the Dunois deanery.
