The Armstrong Siddeley Typhoon was a two-door, four-seat fixed-head coupé car made by the British Armstrong Siddeley company. It was made from 1946 to 1949 and based on the 1945 Armstrong Siddeley Lancaster saloon and continued the company's theme of naming cars after Hawker Siddeley World War II aircraft.

The chassis had independent front suspension using longitudinal torsion bars and a live rear axle with leaf springs. A Girling hydro-mechanical braking system was fitted, with the front drums hydraulically operated while those at the rear used rod and cable.

At first the Typhoon were fitted with a 70 bhp 1991 cc, six-cylinder, overhead-valve engine, carried over from the pre-war 16 hp model, but from 1949 this changed to 2309 cc and 75 bhp by increasing the cylinder bore from 65 to 70 mm. Hydraulic tappets were fitted to most engines, but towards the end of production there was a change to solid tappets. There was a choice of manual four-speed with synchromesh on the top three ratios or pre-selector gearbox.

The four-seat, two-door body was made of steel and aluminium panels fitted over a wood-and-aluminium frame with a fabric roof. The doors were rear hinged, an arrangement that got the name of suicide doors.

At launch, the car cost £1214 on the UK market.
