St. Joseph Cathedral, Catholic cathedral in downtown Baton Rouge, United States.

St. Joseph Cathedral is the third church of a parish founded in 1792, built in downtown Baton Rouge between 1853 and 1856 and designated a cathedral in 1961. Its interior was renovated in 1967 and re-dedicated on September 30, 1970. The building was listed on the National Register of Historic Places on March 22, 1990.

The parish was founded in 1792 as the Parroquia de Nuestra Señora de los Dolores and was renamed after Louisiana became a state in 1812 as English replaced Spanish among the population. The present church, the parish's third, was begun in 1853 and completed in 1856. Pope John XXIII made it the cathedral of the Diocese of Baton Rouge in the bull "Peramplum Novae Aureliae" of July 22, 1961; the diocese was erected on November 8, 1961, with Robert Emmet Tracy as first bishop. A major interior renovation in 1967 led to its re-dedication on September 30, 1970.
