The 2024 NASCAR Xfinity Series was the 43rd season of the NASCAR Xfinity Series, a stock car racing series sanctioned by NASCAR in the United States. The season started on February 19 with the United Rentals 300 at Daytona International Speedway and ended with the NASCAR Xfinity Series Championship Race on November 9 at Phoenix Raceway.

Cole Custer of Stewart–Haas Racing entered the season as the defending NASCAR Xfinity Series champion. Following the 2024 Food City 300 at Bristol Motor Speedway, Custer won the regular season championship. At season's end, Justin Allgaier of JR Motorsports became the 2024 Xfinity Series champion.

This season marked the final year of Fox and NBC's coverage of the Xfinity Series under the 2015–2024 TV contract. Beginning in 2025, The CW will assume exclusive broadcast rights for the entire Xfinity Series schedule as part of a new agreement running through 2031. As a prelude to this transition, it was announced in April 2024 that the final eight races of the 2024 season — including the regular season finale (the Food City 300), and all playoff races — would air on The CW. However, NBC Sports would continue producing the broadcasts for these races.
