Notre-Dame-des-Missions-du-cygne d'Enghien (sometimes referred to as Notre-Dame-des-Missions d'Épinay-sur-Seine) is a French Roman Catholic church located in the commune of Épinay-sur-Seine, near Paris and in the Seine-Saint-Denis department.

It was then reconstructed using more durable materials in 1933[2] in Épinay-sur-Seine; funds for the building's construction were raised through a national subscription spearheaded by Marshal Hubert Lyautey.

[1] The architecture of the church is meant to recall the civilizations that were served by the Christian missions; the building is distinguished from many contemporary works through its use of reinforced concrete.

The whole facade is covered in blue and white ceramic tile in a pattern created by Lorymi and Raymond Virac, using a new type of brickwork developed in 1930 by Marguerite Huré.

[1] Many painters, sculptors and glassworkers participated in the decoration of the inside of the church; most of these artists came from the studios of sacred art founded by Maurice Denis, who had designed the windows for the nearby Notre-Dame du Raincy, and of George Desvallières.

A series of murals, on the right side of the church building, was painted by Raymond Virac, Lucien Simon, and Robert-Albert Génicot; these celebrate the evangelical work done in Indochina and India by Francis Xavier and that done in Japan by Alphonsus Navarette.

Maurice Denis was the most famous artist to contribute to this series; he was aided by Henri-Justin Marret, Valentine Reyre, Paul de Laboulaye, and Georges Ballot.
