The 1984 Monaco Grand Prix was a Formula One motor race held at Monaco on 3 June 1984. It was race 6 of 16 in the 1984 FIA Formula One World Championship. It was the only race of the 1984 championship that was run in wet weather.
Alain Prost won the rain-curtailed race from pole position. Ayrton Senna was second in his first podium in Formula One. René Arnoux was later promoted to third after the disqualification of Stefan Bellof.

Practice
During practice, Tyrrell's Martin Brundle had a huge crash at the Tabac corner. He landed upside down and was slightly injured, but it was enough to make him a non-qualifier for the race. Brundle later said that he ran back to the pits and had actually gotten into the spare car before team boss Ken Tyrrell got on the radio and asked him if he was OK after the accident. It was then discovered that Brundle could not actually remember how he returned to the pits, so the boss wisely would not allow Brundle to go back onto the track and ordered him out of the car. He then took Brundle to see Formula One medical chief Sid Watkins, who after an examination concluded that the rookie driver was slightly concussed and the decision was made to withdraw him from the race weekend.
Qualifying
Alain Prost took his first pole position for McLaren with a time of 1:22.661, just ahead of the Lotus-Renault of Nigel Mansell. Prost's pole was also the first pole for the McLaren MP4/2 as well as for the TAG-Porsche engine. Stefan Bellof was the only non-turbo qualifier in his Tyrrell-Cosworth. Bellof qualified 20th and last while Brundle's crash behind the pits at Tabac saw him as a spectator for the race. Bellof's time edged the Arrows-Ford of Marc Surer by just 0.156. The turbo cars of Eddie Cheever (Alfa Romeo) and Thierry Boutsen (Arrows-BMW) both failed to qualify.
BMW had built specially detuned engines for Brabham to use at Monaco. Instead of the normal 900 bhp (671 kW; 912 PS) engines, the Brabhams only had around 700 bhp (522 kW; 710 PS) to play with, the theory being that full power was not needed at Monaco and the detuned engines would be more drivable. It was also an attempt at better reliability as the team had yet to score a point for the year. Never at ease at Monaco, reigning World Champion Nelson Piquet qualified 9th. With Teo Fabi having commitments to race the US based IndyCars at Milwaukee on the same weekend his brother Corrado Fabi drove the second Brabham, qualifying 15th.
Race
The race, held amidst heavy rain, was one of the most contentious in Formula One history, and announced the emergence of at least two new stars. Alain Prost took the first of his four victories at the circuit.
The race start was delayed by 45 minutes due to the heavy rain. With the rain soaking the track, Niki Lauda sought out Bernie Ecclestone on the grid in a bid to have the tunnel flooded as well. The tunnel was dry but coated with oil from the previous days' use (as well as from the historic cars which were on the program that weekend) which Lauda explained had turned it into a fifth gear skid pad when the cars came racing in carrying the spray from their tyres in the morning warmup. Ecclestone used his power as the head of the Formula One Constructors Association to do exactly that, with a local fire truck called in to water down the only dry road on the track.
Pole-sitter Prost led the race from the start, while first corner contact between Ferrari's René Arnoux and the Renault of Derek Warwick pitched Warwick's car into the fence on the outside of St. Devote and into the path of his team-mate Patrick Tambay. Both drivers suffered leg injuries; Warwick bruised his left leg while Tambay broke his leg after his car's suspension punched through the carbon fibre monocoque, causing him to miss the next round in Canada.
Prost was passed on lap nine by Nigel Mansell, to lead a Grand Prix for the first time, when Prost's TAG engine was misfiring and he was delayed by both Corrado Fabi's stalled Brabham and Michele Alboreto's about-to-be-lapped Ferrari just before the tunnel (Prost actually hit a marshal who was pushing Fabi's car away but with no serious injury). Mansell pulled away from Prost at around two seconds per lap, before going off six laps later on the run up to Casino Square after sliding on a painted white line, damaging his car and retiring from the race.
Lauda disposed of Arnoux but Prost assumed the lead again, only to have the Toleman-Hart of Ayrton Senna, who had also passed the Ferrari, quickly closing in. Senna had started thirteenth in the generally uncompetitive Toleman, in the first Formula One street race in his rookie season, and was showing his wet weather skills that would become legendary. On lap 29, Prost waved to the stewards of the race to indicate that he felt the race should be stopped. He was also suffering from a major brake imbalance as his McLaren's carbon brakes were locking due to not generating enough heat in the conditions, the same problem that had caused Lauda to spin at Casino Square on lap 23, whereupon he stalled his engine and was out of the race. A slowing Prost waved again on lap 31 as he passed the start/finish line.
