Leonidas Polk (April 10, 1806 – June 14, 1864) was a planter in Maury County, Tennessee, US, and a second cousin of President James K. Polk. He was bishop of the Episcopal Diocese of Louisiana. He resigned his ecclesiastical position to become a major general in the Confederate army (called "Sewanee's Fighting Bishop"). His official portrait at the University of the South depicts him dressed as a bishop with his army uniform hanging nearby.
