The knockout stage of the 2007 Rugby World Cup began on 6 October with a quarter-final between Australia and England and concluded on 20 October with the final, at the Stade de France in Saint-Denis, Paris, between England and South Africa, their second meeting in this tournament.

South Africa were the first team to qualify for the knockout stage, when they beat Tonga 30–25 in their penultimate Pool A game.

This was the first Rugby World Cup tournament to have its semi-finalists coming from only two pools (Pools A and D), and the finalists coming from just one pool (Pool A).

The top two representative nations of each of pools B and C were eliminated in the quarter-finals.
