James Robert "Jim-Bob" Walton (born June 13, 1924) is the youngest Walton boy, and the 6th child of Olivia Walton and John Walton. His twin, Joseph Walton, died at birth.
James Robert is referred to as "Jim-Bob" and, although he tries to shake it off as he gets older, the nickname sticks. In later episodes he wants joins the Air Force as soon as he can and even has his own aviation helmet. Jim-Bob built a car from scratch, and it runs decently, although it does have occasional problems. He gets in a lot of fights with Ben. In the episode The Home Front he dates adoptive cousin Aimee Godsey.
