The Alfa Romeo 184T is a Formula One car which competed during the 1984 and 1985 Formula One seasons. It was developed by the Alfa Romeo Team. The car, which was Mario Tollentino's first F1 design, bore the colours of the team's major sponsor Benetton.

The car, which had a 1.5 L V8 turbo engine, producing around 680 hp (507 kW) at 10700 rpm, achieved a total of 11 points, all in 1984. The car's best result was at the 1984 Italian Grand Prix, where Riccardo Patrese came 3rd, at team mate Eddie Cheever's expense as the American was running 3rd, but ran out of fuel. Most of the 184T's retirements were due to the unreliability of the engine, or running out of fuel (in 1984 and 1985, Formula One regulations restricted turbo powered cars to only 220L of fuel per race).

The 184T was replaced for 1985 by the 185T, but the car proved to be uncompetitive so the 184T was brought out of retirement, updated to 1985 regulations and was dubbed the 184TB.
