The fifteenth season of American Ninja Warrior premiered on June 5, 2023, on NBC. A spin-off from the Japanese reality series Sasuke, it is hosted by Matt Iseman, Akbar Gbaja-Biamila, and Zuri Hall. This season, both Qualifying and Semifinals were entirely held in Universal City in Los Angeles, while the National Finals returned to its usual spot in Las Vegas.

This season set a new record with 8 competitors all advancing to Stage 4, and also crowned the third grand prize winner in Vance Walker, who not only became the fifth ninja to achieve "Total Victory", but had previously won American Ninja Warrior Junior twice. In the same season, Daniel Gil became the fourth ninja to achieve total victory, but completed the rope climb slower than Walker.

The season was officially announced by NBC in late March 2023, though the applications were being accepted from November 19, 2022, until December 16, 2022. The full list of competitors was published on March 15, 2023. Filming for qualifiers moved to Los Angeles, California, where the semifinals remained. Filming for national finals remained in Las Vegas, Nevada.

Filming for the season began on March 15, 2023, and wrapped in early May 2023.

Obstacles The qualifying course starts from Pole Vault and ends on Warped Wall. For this season, to get one attempt for the Mega Wall, which was increased to 18.5 feet high, contestants must finish the course in less than 1 minute and 20 seconds; a contestant who completes the Mega Wall still gets an immediate reward of $10,000 (promoted by Wells Fargo). Standing next to the main course is a new segment, "The Runoffs", which replaces the Power Tower but follows the same structure: it features four obstacles, with two copies of them located alongside each other. The two male contestants and two female contestants in the last two places on the leaderboard run it side by side for the last spot in the semifinals.

In the semifinals, two contestants will run against each other, side-by-side, on the previously installed Runoffs course with Slingshot and Rope Climb added as a last two obstacles. At the end of the night, the two fastest finishers will run on a Safety Pass course, which replaces some of the obstacles from Semifinals with other ones. The winner receives a Safety Pass which allows for a do-over of stage 1 in the National Finals if he or she fails.

Qualifying The eight qualifiers, divided into seven nights, took place on the lot of Universal Studios Hollywood in Los Angeles, California. In a major change from past seasons, the number of semifinalists has been reduced, and men and women have completely separate leaderboards. The top 11 men and top 3 women advance to the semifinals immediately, while the next two men (12th/13th place) and the next two women (4th/5th place) compete head-to-head in "The Runoffs" for the final spots.

Course 1 The first night of qualifying featured two rounds that were held in order. 5 competitors completed Course 1; only two of the competitors managed to finish the course faster than 1 minute and 20 seconds, but neither were able to successfully scale the Mega Wall. In the runoffs, Ramcis Valdez beat Alan Connealy (who made his first appearance since season 9) for the last men's spot, while Taylor Johnson beat Avery Glantz for the last women's spot. New obstacles included the Pole Vault, The Getaway, Lasso Launch, and Home Run in the runoff course. In an emotional moment, Brian Kretsch (who is one of only two competitors to appear in every single season) once again fell on a balance obstacle in the qualifying course (in this case, Domino Effect), and in his post-run interview, he hinted at a possible retirement from competition, citing his continued inability to clear balance obstacles.

Course 2

Course 2 occurred on the same night as the first qualifying, with 6 competitors finishing it. Top men's finisher Kai Beckstrand became the first competitor to complete this season's taller Mega Wall, and second-place finisher Jera Boyd was the other Mega Wall finisher. In the runoffs, Glenn Albright beat Steven Bachta for the last men's spot, while Jaelyn Bennett beat Larissa Cottle for the last women's spot. New obstacles in the qualifying course included Greased Lightning and Ring the Bells.

Course 3

Only two competitors completed Course 3. Daniel Gil, who returned after missing the previous season, took the top time for the men and cleared the Mega Wall. In the runoffs, Gary Weiland beat James Thorwart for the last men's spot after completing the balance obstacle and became the first amputee ever to move on to the semi-finals. The qualifying course introduced another new obstacle, Kite Surfer.

Course 4

Four competitors finished Course 4, but neither of the two who cleared it faster than 1 minute and 20 seconds managed to scale the Mega Wall. Jessie Graff returned again, and for the first time, her mother, 71-year-old Ginny MacColl, also competed (and ultimately failed the second obstacle, Greased Lightning). Brothers Nacssa and Roberto Garemore, who first appeared on American Ninja Warrior Junior, made their main ANW debuts and both advanced to the semi-finals. Firefighter Brandon Mears, one half of the duo called the "Towers of Power", returned after missing last season and announced that he would be making his final run on the course, but ultimately failed on Greased Lightning. This course introduced another new obstacle called The Cubes.

Course 5

Course 5 was finished by 5 competitors; of those that cleared, only reigning two-time champion (Last Ninja Standing both times) Kaden Lebsack, cleared the course fast enough to try the Mega Wall, but failed to scale it. Former American Ninja Warrior Junior contestant Taylor Greene competed on the main course for the first time after turning 15 and became the first and only woman to clear the qualifying course this season. Two veterans, Jackson Twait and Donovan Metoyer, tried to run the course speedily to get a chance to try the Mega Wall, but both failed with the latter being eliminated after he fell on Domino Effect.

Course 6

Course 6 was completed by 3 competitors. Sean Bryan took the fastest time and was the only competitor to clear the course fast enough to try the Mega Wall, but his attempt to scale it was ultimately unsuccessful. David Campbell competed again to keep his status as one of only two competitors to appear in every season of the show alive and once again managed to qualify for the semi-finals. Other notable competitors included West Side Story visual effects designer Daniel Novarro, who received encouragement from two of the film's stars, Rachel Zegler and Josh Rivera, before the start of his run (Novarro was ultimately defeated in the runoffs by police officer John Uga), and veteran Nate Tackett, who advanced to the semi-finals after receiving encouragement from his cousin, legendary country music singer Crystal Gayle.
