The ninth Inter-Cities Fairs Cup was played over the 1966–67 season. The competition was won by Dinamo Zagreb over two legs in the final against Leeds United. For the first time in the history of the cup, replays were scrapped, with sides going through thanks to scoring more away goals, or by tossing a coin after extra time if the sides could not be separated. Dinamo benefitted from both in the early rounds.
