The 1984 Dutch Grand Prix was a Formula One motor race held at Zandvoort on 26 August 1984.

The 71-lap race was won by Frenchman Alain Prost, driving a McLaren-TAG, after he started from pole position.

His Austrian teammate Niki Lauda finished second, with Briton Nigel Mansell third in a Lotus-Renault.

Before the race, it was rumoured that Ayrton Senna would break his contract with the Toleman team and join Lotus for 1985.

It was also correctly rumoured that, with Jacques Laffite already known to be leaving Williams at the end of the season to return to Ligier, team owner Frank Williams had signed Mansell for 1985 alongside Keke Rosberg after his original choice Derek Warwick had decided to stay with the Renault team.
