The 2023 24 Hours of Daytona was an endurance sports car race sanctioned by the International Motor Sports Association (IMSA). The event was held at Daytona International Speedway combined road course in Daytona Beach, Florida, on January 28–29, 2023. This event was the 61st running of the 24 Hours of Daytona since its inception in 1962, and the first of 11 races across multiple classes in the 2023 IMSA SportsCar Championship, as well as the first of four rounds in the 2023 Michelin Endurance Cup. The No. 60 Meyer Shank Racing Acura, driven by Tom Blomqvist, Colin Braun, Hélio Castroneves and Simon Pagenaud, took the overall win, but the team was later penalized for tire pressure data manipulation, resulting in penalties, fines and probation for those responsible. This was Meyer Shank's second Rolex 24 win in a row, and their third major endurance race win in four events. The No. 10 Wayne Taylor Racing Acura finished second overall and scored the most points towards the GTP championship.
