The 1912 College Football All-Southern Team consists of American football players selected to the College Football All-Southern Teams selected by various organizations for the 1912 Southern Intercollegiate Athletic Association football season. Lew Hardage was selected for Walter Camp's third-team All-American. Vanderbilt won the SIAA championship. Georgetown won the SAIAA championship.

Innis Brown, a referee throughout the south, and captain of Vanderbilt's 1905 championship team, was hired to select the team of the Atlanta Constitution. The Constitution's editor Dick Jemison also selected a team. Former Georgia player and captain and then assistant Harold Ketron selected a team. Georgia Tech head coach John Heisman as usual picked one also. Former Mississippi head coach Nathan Stauffer selected an All-Southern team for Collier's Weekly.

The composite All-Southern eleven formed by "consolidated pick" of ten sporting writers culled by the Atlanta Constitution editor Dick Jemison included:

• Rube Barker, tackle for Mississippi. Later, he was a practicing physician in Oakland, Illinois.^[1]
• Enoch Brown, end for Vanderbilt. Known as "Nuck," he was a Rhodes Scholar.^[2]
• Tom Brown, tackle for Vanderbilt. He played with the Toledo Maroons and was later a physician. "He had no peers in his orthopedic ability and contributed greatly to Toledo medicine."^[3]
• Jenks Gillem, end for Sewanee. He was a renowned punter and kicker,^[4] selected as the punter for the Associated Press Southeast Area All-Time football team 1869-1919 era.^[5] He later coached.
• Lew Hardage, halfback and senior-captain for Vanderbilt, unanimous selection, was also selected third-team All-American by Walter Camp, the fourth ever Southern player to get such a recognition.^[6] Innis Brown in 1912 wrote "Hardage has been rated as probably the most successful man in the south at making forward passes."
• B. J. Lamb, tackle for Auburn. Known as "Sheep," he practiced tackling on trees.^[7]
• Bob McWhorter, halfback for Georgia, unanimous selection. He was the school's first All-American, inducted into the College Football Hall of Fame in 1954. Sportswriter Dick Jemison said "When you mention football to an Athens fan its definition is Bob McWhorter, and vice-versa."^[8] He was selected for the Associated Press Southeast Area All-Time football team 1869-1919 era.^[5] McWhorter went on to have a lengthy law career.
• Hugh Morgan, center for Vanderbilt, unanimous selection. Chosen "by a good margin" wrote Brown.^[4] Later, he was a world-renowned internist and medical professor.
• David Peacock, guard for Georgia. Known as "Emp," was an assistant coach for his alma mater in 1914. He was once president pro-tempore of the Georgia state Senate.^[9]
• Ammie Sikes, fullback for Vanderbilt. Brown chose him for his speed.^[4]
• Lee Tolley, quarterback for Sewanee. Later, he was a Southeastern Conference official.^[10]
