The knockout stage of the 1997–98 UEFA Champions League began on 4 March 1998 and ended with the final at the Amsterdam Arena in Amsterdam on 20 May 1998. The eight teams from each of the six groups in the group stage competed in the knockout stage. For the quarter-finals, each group winner was randomly drawn against the runner-up from another group. The four quarter-final winners were then drawn together for the semi-finals, the winners of which contested the final.
