Britain's Next Top Model, Cycle 3 was the third cycle of Britain's Next Top Model and the third series aired on Living.

For this cycle the judges remain the same as they did during last series. The number of contestants was decreased to 12, the same number of contestants as Cycle 1. The opening credits received a makeover and the theme song was also changed.

The international destination for this cycle was Rio de Janeiro, Brazil. The winner's prize was management and representation by Models 1, a contract with Ruby & Millie Cosmetics and a cover and 6-page spread in Company Magazine.

The winner of the competition was 20 year-old Lauren McAvoy from Wickford, Essex.

Runner-up Louise Watts participated as a contestant on America's Next Top Model, Cycle 18 along with six other former BNTM contestants. Watts quit the competition in the 3rd episode because she felt she couldn't handle the negative criticism of the judges, particularly Kelly Cutrone.
