The 1989 Portuguese Grand Prix (formally the XXIII Grande Prémio de Portugal) was a Formula One motor race held at the Autódromo do Estoril in Estoril, Portugal on 24 September 1989. The 71-lap race was the thirteenth of the 1989 Formula One season and was won by Gerhard Berger, driving a Ferrari, with Alain Prost second in a McLaren-Honda and Stefan Johansson third in an Onyx-Ford. Prost's team-mate and Drivers' Championship rival, Ayrton Senna, retired following a collision with the second Ferrari of Nigel Mansell, who had been black-flagged for reversing in the pit lane; as a result, Prost moved 24 points clear of Senna in the championship with three races remaining.
As well as Johansson taking Onyx's only podium finish, the race also saw Pierluigi Martini lead for one lap, the first and only time the Minardi team led a Formula One race, and ten drivers from ten different teams finish in the top ten places. The race was also Prost's 150th Grand Prix start and the last start for the Coloni team, though it would continue in F1 until the end of 1991.
