The Benetton B186 is a Formula One racing car, built and raced by the Benetton team for the 1986 Formula One World Championship. It was the first car to be constructed and raced by Benetton, which had bought the Toleman team at the end of 1985 after several years of sponsoring it and other teams, including Alfa Romeo and Tyrrell.

Benetton Formula Ltd., commonly referred to simply as Benetton, was a Formula One constructor that participated from 1986 to 2001. The team was owned by the Benetton family who run a worldwide chain of clothing stores of the same name. In 2000, the team was purchased by Renault, but competed as Benetton for the 2000 and 2001 seasons. In 2002, the team became Renault. The Benetton Formula team was chaired by Alessandro Benetton from 1988 to 1998.
