Dainotti was an Italian car manufacturer based in Pavia, operating under the name Fabbrica Automobili Dainotti.
The marque was notable for producing small cars powered exclusively by straight-eight engines, an unusual configuration for vehicles of that size. One model used a 1,492cc two-stroke straight-eight engine, while a larger version was fitted with a 2-litre four-stroke straight-eight and was credited with a top speed of 75 mph (120 km/h).
