List of SIAA football champions
The list of SIAA football champions includes the teams that have won the college football championship of the Southern Intercollegiate Athletic Association since its creation. Twenty-seven of the current Division I FBS football programs were members of this conference at some point, as were at least 19 other schools. Every member of the current Southeastern Conference except Arkansas and Missouri, as well as six of the 15 current members of the Atlantic Coast Conference plus the University of Texas at Austin, now of the Big 12 Conference, formerly held membership in the SIAA.
Champions by year
Championships of the SIAA were not officially awarded by the SIAA itself and were instead more mythical in nature, being a combination of which school were recognized as the consensus champion and what seasons the schools themselves choose to claim. In the 27 years before 1922, when many schools left the SIAA to form the Southern Conference, Vanderbilt claimed 11 SIAA titles. Auburn and Georgia Tech share second place with 7 SIAA titles each.1896 to 1921
| Year | Championship team | Conference Record | Notes |
| 1896 | Georgia LSU | 3–0 4–0 | Georgia was coached by Glenn "Pop" Warner and led by Richard Von Albade Gammon, who died from injuries sustained against Virginia the following year. Cow Nalley was also on the team, Georgia's only five-year letterman. The 1896 LSU team was the first to use the nickname "Tigers". |
| 1897 | Vanderbilt | 3–0 | Vanderbilt shut out all opponents and won its first SIAA title. Phil Connell, Howard Boogher, and Lucius E. Burch played for Vanderbilt. A game against Virginia was scheduled for the championship of the South, and ended in a scoreless tie. |
| 1898 | Sewanee | 3–0 | Only rival Vanderbilt's Walter H. Simmons scored on Sewanee. |
| 1899 | Sewanee | 11–0 | Led by captain Diddy Seibels and known as the "Iron Men," Sewanee was undefeated and shutout Texas, Texas A&M, Tulane, LSU and Ole Miss over a 6-day span. Only Auburn, coached by John Heisman, scored points on Sewanee. |
| 1900 | Clemson | 3–0 | Clemson's first outright SIAA title. Heisman's first undefeated and untied season as a head coach. The 64–0 win over Davidson on opening day was then the largest score ever made in the South. |
| 1901 | Vanderbilt | 5–0–1 | Vanderbilt defeated the best University of Nashville team in the school's history to close the season and secure the title. |
| 1902 | Clemson LSU | 5–0 5–1 | Clemson's only loss was to rival South Carolina, in a controversial game ending in riots and banning the contest until 1909. Despite losing to Vanderbilt, LSU also claims a title. |
| 1903 | Clemson Cumberland | 4–0–1 4–1–1 | Clemson was the favorite as champions, but played in a postseason "SIAA championship" and tied Cumberland. Heisman pushed hard for Cumberland to claim a title. |
| 1904 | Auburn Vanderbilt | 4–0 4–0 | Mike Donahue's first year coaching at Auburn, and Dan McGugin's first year coaching at Vanderbilt. McGugin remains the only coach in NCAA history to win his first three games by 60 points. |
| 1905 | Vanderbilt | 6–0 | Vanderbilt's only blemish was an 18–0 loss to Michigan. |
| 1906 | Clemson Vanderbilt | 4–0–1 6–0 | Clemson had one of the south's best defenses, allowing no touchdowns. Some writers selected Vanderbilt as the entire All-Southern eleven. Vanderbilt beat Carlisle 4–0. |
| 1907 | Vanderbilt | 4–0 | Vanderbilt tied Navy, and defeated a powerful Sewanee on a double pass which Grantland Rice called his "greatest thrill" in his years of watching sport. |
| 1908 | Auburn LSU | 5–1 3–0 | Though the school does not recognize it, LSU was retroactively awarded a national championship by the National Championship Foundation. Doc Fenton led the nation in scoring. The season was clouded by accusations of professionalism from rival Tulane. As a result, most sportswriters did not include LSU for consideration as conference champions. Auburn was most popular among those who listed an alternative SIAA champion. |
| 1909 | Sewanee | 5–0 | Sewanee was led by first-year head coach Harris Cope and handed Vanderbilt its first loss to a southern team in 6 years. Rice called Aubrey Lanier "the noblest Tiger of them all." |
| 1910 | Auburn Central Vanderbilt | 4–0 3–0 5–0 | Auburn's leading scorer was Bill Streit. Vanderbilt tied Yale, the first time Yale had been held scoreless at home, and the South's first great showing against an Eastern power. Central also claimed a title, since Vanderbilt did not play them. |
| 1911 | Vanderbilt | 5–0 | Edwin Pope's Football's Greatest Coaches notes: "A lightning-swift backfield of Lew Hardage, Wilson Collins, Ammie Sikes, and Ray Morrison pushed Vandy through 1911 with only a 9–8 loss to Michigan." The Atlanta Constitution voted it the best backfield in the South. |
| 1912 | Vanderbilt | 4–0–1 | Vanderbilt tied Auburn and suffered its only loss to national champion Harvard. |
| 1913 | Auburn | 8–0 | Led by Kirk Newell, Auburn won a national championship according to the Billingsley Report adjusted for margin of victory. |
| 1914 | Auburn Tennessee | 7–0 5–0–1 | Auburn's defense was led by Bull Kearley and did not allow a point. Tennessee beat rival Vanderbilt for the first time and won its first championship of any kind. The 1914 Vols were retroactively awarded a national championship by 1st-N-Goal, though this remains largely unrecognized. |
| 1915 | Vanderbilt | 4–0 | Seven out of eight newspapers voted the SIAA championship to the Commodores. The Atlanta Constitution declared it a tie between Vanderbilt and Heisman-coached Georgia Tech, which was then independent. |
| 1916 | Georgia Tech Tennessee | 5–0 6–0–1 | Tech beat Cumberland 222–0. Because of World War I, Tennessee did not field another varsity squad until 1919. The New York Herald ranked Buck Hatcher as the season's premier punter. Graham Vowell was the season's only unanimous All-Southern selection. |

| 1920 | Georgia Georgia Tech Tulane | 8–0 5–0 4–0 | Georgia led by its "ten second backfield" and strong line was selected for a national championship by Clyde Berryman. Tech's only loss was a controversial one to Pop Warner's Pittsburgh. Florent Gibson of the Pittsburgh Post rated Tech as the best team in the country. Tech also handed Centre its first loss to a southern team since 1916. Tulane's team was led by Clark Shaughnessy and was the first called the "Green Wave". |
| 1921 | Centre Georgia Georgia Tech Vanderbilt | 5–0 6–0–1 5–0 5–0–1 | Red Barron rushed for 1,459 yards, a Georgia Tech record at the time. Tech's only loss was to Penn State at the Polo Grounds. Vanderbilt tied Georgia at the end of the game on an onside kick from scrimmage. Vanderbilt was selected for a national championship by Clyde Berryman. |
1922 to 1941
The SIAA continued to exist for another 19 years. In this period the Chattanooga Mocs managed the most titles, coming away with four. At the SIAA annual convention in 1930, nine of the association's members announced the formation of the Dixie Conference to facilitate scheduling of games among the group. The charter members were Birmingham-Southern College, Howard College, Southwestern of Memphis, Centre College, University of Chattanooga, Spring Hill College and Mercer University; Loyola University New Orleans joined the Dixie two years later.At the time of formation, conference president Dean G. W. Meade of Birmingham-Southern stated, "We are still members of the S. I. A. A. and will continue to be so." However, at the SIAA convention the following year, Birmingham-Southern, Howard and Spring Hill resigned from the association. University officials at Chattanooga announced their resignation from the SIAA in 1932, explaining that they "saw no purpose in remaining in the unwieldy association after successful launching of the Dixie Conference two years ago".
Two years prior to the SIAA, the Dixie Conference approved the use of scholarships in 1936.
