The fifteenth series of the Australian cooking game show MasterChef Australia premiered on 7 May 2023 on Network 10 and concluded on 16 July 2023.
The series was originally announced at Paramount's and Network 10's upfronts in October 2022. Subtitled Secrets & Surprises, the season featured 18 contestants, with 17 new to the show. Andy Allen, Melissa Leong, and Jock Zonfrillo returned to the show as judges from the previous season. The series was originally scheduled to premiere on 1 May 2023. However, following Zonfrillo's death on 30 April, the premiere was postponed until 7 May. Filming of the season had been completed in March 2023 and was thus unaffected by the death of Zonfrillo. The premiere was preceded by a special edition of The Sunday Project that paid tribute to Zonfrillo.
The series was won by Brent Draper, who previously appeared in series 13 but withdrew for mental health reasons.
