The 2023 Next Gen ATP Finals was a men's exhibition tennis tournament for the eight highest-ranked singles players on the 2023 ATP Tour aged 21 and under, held from 28 November to 2 December 2023 at King Abdullah Sports City in Jeddah, Saudi Arabia. In a dramatic five-set final, Hamad Medjedovic of Serbia defeated Arthur Fils of France with a score of 3–4(6–8), 4–1, 4–2, 3–4(9–11), 4–1 to claim the title. The defending champion, Brandon Nakashima, was ineligible to defend his crown because he had aged out of the competition (players must be born in 2002 or later). Qualification was determined by the top seven players in the ATP Race to Jeddah, plus one wildcard, ensuring a showcase of the sport's brightest emerging talents. The event serves as a critical stepping-stone for the ATP's next generation, highlighting the fast-paced, promising future of men's professional tennis.
