Jones, an offensive lineman who is listed at 6-5, 311 pounds, made the announcement after practice Friday.
Alabama will take on LSU Jan. 9 in New Orleans for the national championship. Jones received the Outland Trophy -- as the nation's top interior lineman -- three weeks ago.
"I sat down with my family and made a list of pros and cons and decided I love college," Jones said. "I love being at Alabama and I love putting on the crimson jersey. I have a great group of friends and I am in no hurry to get to the NFL. I do want to play in the NFL one day, but I am not in any rush."
Jones has helped clear running lanes for Heisman Trophy finalist Trent Richardson, who has gained 1,583 yards and scored 20 touchdowns this season.
