The 2017 CAF Confederation Cup knockout stage was played from 8 September to 25 November 2017. A total of eight teams competed in the knockout stage to decide the champions of the 2017 CAF Confederation Cup.
Qualified teams
The winners and runners-up of each of the four groups in the group stage advanced to the quarter-finals.
In the knockout stage, the eight teams played a single-elimination tournament. Each tie was played on a home-and-away two-legged basis. If the aggregate score was tied after the second leg, the away goals rule would be applied, and if still tied, extra time would not be played, and the penalty shoot-out would be used to determine the winner (Regulations III. 26 & 27).
