Idols South Africa IV is the fourth season of South African reality television series Idols South Africa. Idols South Africa is a competitive talent show based on Pop Idol in the United Kingdom. Idols South Africa IV premiered in September 2007 after a one-year hiatus.
The judging panel remained the same for the third season in a row; Colin Moss returned for what was to be his final season. As in previous seasons, each performer's score is an aggregate of the audience's votes (51%) and the judges' votes (49%).
The winner was 17-year-old Jody Williams, who bested Andriëtte Norman on 9 December 2007, at Ellis Park Stadium in Williams' hometown of Johannesburg. Williams was the youngest winner of the show to date, and she was the third consecutive woman to be named "SA Idol". Her winning song was a cover of "Love Is All Around" by Swedish singer Agnes Carlsson. (Carlsson was previously named the winner of Sweden's Idol 2005.)
Ages are as stated in the contest.
The first four weeks are the semi-finals, followed by nine weeks of finals.
