Église Saint-Eugène-Sainte-Cécile is a Roman Catholic church located at 6 rue Sainte-Cécile in the 9th arrondissement of Paris.

Designed in the Neo-Gothic style by Louis-Auguste Boileau and Louis-Adrien Lusson, the church was the first in France to use an entirely iron-framed construction.

[4] The parish of Saint-Eugène was created in 1854 to serve the growing population of the Faubourg Poissonnière district, at the time considered a suburb of Paris.

Boileau had previously written a treatise on monumental architecture in which he championed the use of iron frame construction.

The arcades of thick stone columns and pillar which separate the nave from the collateral aisles in traditional Gothic churches have been replaced by rows of tall, slender iron columns painted in vivid blues reds and greens, which form arcades with pointed arches high overhead.

The windows on the upper level are by Gaspard Gsell [fr] and depict scenes from the private and public life of Christ including his pardoning of an adulteress, and his betrayal by Judas.

The chapel of the baptistry has a particularly elegant baptismal font, featuring angels and a demon, in with forms which suggest the soon-to-arrive Art Nouveau style.

The grand pipe organ was built by Joseph Merklin and had been exhibited at the 1855 Exposition Universelle in Paris prior to being installed in the church.

[2][5][10] Clergy associated with Saint-Eugène include Albert Le Nordez who gave conferences for Christian women there in the 1890s and Jean-Pierre Batut who was the church's pastor from 2007 to 2009.
