Celebrity MasterChef Australia is an Australian competitive cooking game show. It is spin-off of MasterChef Australia, itself an adaptation of the British show MasterChef, and features celebrity contestants. It began production in early September 2009, and premiered on Network Ten on 30 September 2009.

Matt Preston, George Calombaris and Gary Mehigan returned as judges for the show; however Sarah Wilson did not reprise her role as host from the first season of MasterChef Australia. Instead Calombaris and Mehigan will also serve in a general hosting capacity.

Olympic swimmer Eamon Sullivan won the series, taking home $50,000 for charity Swim Survive Stay Alive.

In February 2010, executive producer Mark Fennessy stated that he doubted the spin-off will return for a second season.
