St. Joseph Co-Cathedral is a Catholic cathedral located in Thibodaux, Louisiana, United States.

[2] St. Joseph Parish first began to organize in 1813 and was founded as a mission to Assumption Church in Plattenville in 1817.

The relics of Saint Valerie survived the fire and are in the current church in a glass sarcophagus.

[4] The coat of arms for Pope Pius XI and Archbishop John Shaw of New Orleans are also found there.

A crest appears on all the columns with an emblem of faith, hope, charity and the Ship of Life.
