The knockout stage of the 2017 FIFA Confederations Cup began on 28 June with the semi-final round, and concluded on 2 July 2017 with the final at the Krestovsky Stadium in Saint Petersburg.
The top two teams from each group advanced to the knockout stage to compete in a single-elimination style tournament.
A third-third-place play-off also took place and was played between the two losing teams in the semi-finals.
In the knockout stage, if a match was level at the end of normal playing time, extra time was played (two periods of 15 minutes each), where each team was allowed to make a fourth substitution.
If still tied after extra time, the match was decided by a penalty shoot-out to determine the winners.
