The Roman Catholic St. George's Church (French: Église Saint-Georges) is the most important [citation needed] religious building of the city of Haguenau in Alsace, France.

A first church building, started in 1143, was replaced around 1200 by a flat-roofed basilica with columns, recalling the architecture of Hirsau Abbey and the influence of the Romanesque architecture of Swabia, rather than the Upper Rhine regions and Alsace where basilicas were predominantly domed.

From 1250 to 1283, an expansion in Gothic style took place: a polygonal choir and transept and an octagonal crossing tower were added to the Romanesque nave, which remained intact, and the aisles were covered with a cross-ribbed vault.

During the French Revolution and the fighting around the city in 1945, the church suffered losses in construction and decoration material.

Most noteworthy inside of the Church are the pulpit from the year 1500 by Veit Wagner, a huge crucifix (4 meters high, 2.75 meters wide) [2] from the year 1488 by Klemens von Baden, a twelve-meter-high tabernacle from 1523 by Friedrich Hammer,[3] and several carved altars, including a large-scale work by Diebold Martin, a Last Judgment, to which in the 19th century two late-Gothic paintings by a Franconian or Swabian Anonymous master were added, composing an altar which had originally not been designed in this form.
