Horace Orlando Ivory (born August 8, 1954) is a former American football running back in the NFL from 1977 through 1982. He attended Nolan Catholic High School from 1968 to 1972 where he was a TCIL All-State Running Back. He was offered a football scholarship to Notre Dame University but for academic reasons, went to Navarro Junior College before transferring to the University of Oklahoma for his junior and senior seasons. In his junior year, he scored the winning touchdown against the Texas Longhorns and in his senior year, his touchdown late in the game tied the score. A botched extra point prevented Oklahoma from winning.
