Philippe Pierre Streiff (26 June 1955 – 23 December 2022) was a French racing driver and motorsport executive, who competed in Formula One from 1984 to 1989.

Philippe Pierre Streiff was born on 26 June 1955 in La Tronche, Isère, France.

A pre-season testing crash at the Jacarepaguá circuit in Rio de Janeiro in 1989 with AGS[2] left him a quadriplegic and thus using a wheelchair, with the quality of the care he received in the aftermath having been called into question,[3] even if the accident itself was so serious the roll-bar broke on impact.

[4] Streiff organised the Masters of Paris-Bercy, a kart racing competition held in collaboration with the FFSA, from 1993 to 2001.

In early 1994, Streiff made a bid to purchase Ligier in partnership with Hughes de Chaunac.
