St. Paul's Cathedral, Episcopal cathedral in Oklahoma City, United States

St. Paul's Cathedral is an Episcopal cathedral in Oklahoma City, designed by Arthur J. Williams in the Norman Gothic style. Its exterior has a Norman-style tower, while the interior holds two Tiffany windows behind the altar. The altar, pulpit and baptismal font are carved from Carrara marble, and stained glass on the Gospel side depicts St. John, St. Paul and St. Luke.

St. Paul's began as a mission in 1891, meeting in several locations including the federal courthouse. Its first frame building went up in 1893, and the mission became a parish on May 14, 1902. The cornerstone of the present church was laid in 1903, the first service was held on March 13, 1904, and the Diocese of Oklahoma made it its cathedral in January 1909.

St. Paul's became the cathedral of the Episcopal Diocese of Oklahoma in January 1909, when the diocese elected it to that role. The congregation reported 1,104 members in 2015 and 1,015 in 2023, with average Sunday attendance of 251 in 2024. Its outreach programs are housed in a facility built after the 1995 bombing.

The building sits in a central location in the city and is easily accessible from the street. Visitors will find doors open for quiet reflection and prayer outside of scheduled service times.

The 1995 bomb at the Alfred P. Murrah Federal Building shattered the Celtic Cross atop the church, lifted the roof and splayed the walls outward. The cathedral closed for two years; rebuilding and a new outreach facility cost $7.5 million.
