The Celebrity Apprentice is the seventh installment of the reality game show, Celebrity Apprentice. This season features celebrity candidates vying for the title of Donald Trump's, "Best Business Brain," as a way to revitalize the series, with the winner donating their proceeds to charity.

The series premiered on NBC on January 3, 2008 at 9:00PM.
