The 1986 FIFA World Cup knockout stage was the second and final stage of the 1986 FIFA World Cup finals in Mexico. The stage began on 15 June 1986, and ended with the final at the Estadio Azteca in Mexico City on 29 June 1986. The ties in each round were played over a single match; in the event that scores were level after 90 minutes, the teams would play an additional 30 minutes of extra time, divided into two 15-minute halves, to determine the winner. If the scores remained level after extra time, the teams would contest a penalty shootout.
