The 2023 Tulane Green Wave football team represented Tulane University in the American Athletic Conference (AAC) during the 2023 NCAA Division I FBS football season. The Green Wave were led by Willie Fritz in his eighth and final year as head coach. They played their home games at Yulman Stadium in New Orleans, Louisiana. They entered this season as the defending AAC champions.
On December 3, Fritz was hired as the head coach for the Houston Cougars. Offensive coordinator Slade Nagle was named interim coach for the Military Bowl. On December 9, Troy head coach Jon Sumrall was named as the Green Wave's new head coach.
The Tulane Green Wave football team drew an average home attendance of 25,021 in 2023.
Jim Svoboda, Tulane's former offensive coordinator, parted ways with the team after one season. To replace him, Willie Fritz promoted seventh-year tight ends coach Slade Nagle to offensive coordinator, now Tulane's fourth offensive coordinator in as many years.
Chris Hampton, Tulane's former defensive coordinator, was hired by Oregon as a co-defensive coordinator. Lance Guidry was hired as his replacement on January 20, 2023, although Guidry left the job 18 days later for the same position at Miami. On February 16, Tulane announced their new defensive coordinator to be Shiel Wood, the former defensive coordinator at Troy.
Tulane would lose some outgoing players to the National Football League draft in the offseason: Tyjae Spears and Dorian Williams were both drafted in the third round of the 2023 NFL draft. Nick Anderson, Larry Brooks, Macon Clark, Tyrick James, Will Wallace, Duece Watts, Shae Wyatt, and Lummie Young IV were all signed to the NFL as undrafted free agents as well. However, co-captains Michael Pratt and Sincere Haynesworth announced they would return to Tulane for the 2023 season.
The preseason AAC poll was released on July 25, 2023.
