The 2023–24 Big Bash League season or BBL|13 (also known as KFC Big Bash League 2023 for sponsorship reasons) was the thirteenth season of the Big Bash League (BBL), the professional men's Twenty20 domestic cricket competition in Australia. It started on 7 December 2023 and the final was played on 24 January 2024, with Brisbane Heat defeating Sydney Sixers to win their second BBL title.
The season was shorter than the previous season, with a total of 44 matches. This was in response to concerns that the previous 61 match season was too long.
