The Dino 206 S is a sports prototype produced by Ferrari in 1966–1967 under the Dino marque. Ferrari intended to produce at least fifty examples for homologation by the CSI in the Sport 2.0 L Group 4 category. As only 18 were made, the car had to compete in the Prototype 2.0-litre class instead. In spite of this handicap the Dino 206 S took many class wins. The 206 S was the last of the Dino sports racing cars and simultaneously the most produced.

Dino was a marque best known for mid-engined, rear-drive sports cars produced by Ferrari from 1957 to 1976. The marque came into existence in late 1956 with a front-engined Formula Two racer powered by a brand new Dino V6 engine. The name Dino was used for some models with engines smaller than 12 cylinders, it was an attempt by the company to offer a relatively low-cost sports car. The Ferrari name remained reserved for its premium V12 and flat-12 models until 1976, when "Dino" was retired in favour of full Ferrari branding.
