Joseph Alexander Mabry, Jr. (January 26, 1826 – October 19, 1882) was an American folk figure and businessman active primarily in Knoxville, Tennessee, in the mid-nineteenth century. Mabry earned a fortune through land and railroad speculation during the 1850s, and was known throughout the South for his herd of race horses. During the Civil War, Mabry donated a large supply of uniforms and tents to the Confederate Army, and was rewarded with the rank of general. For the remainder of his life, he was thus often referred to by the sobriquet, "General Mabry."
