Georges-Francis "Johnny" Servoz-Gavin (18 January 1942 – 29 May 2006)[1] was a French motor racing driver in both sportscars and single seaters.

He had previously attended the racing drivers' school at the Magny-Cours circuit in the centre of France, (from which he was "thrown out")[3] and in 1965 entered the French Formula Three Championship in a private Brabham BT18.

He also impressed at the Monaco Grand Prix, entering as Jackie Stewart's stand-in, starting from the front row of the grid,[1] and leading from Graham Hill at the start, until his race ended early after clipping a barrier and breaking a driveshaft in a similar incident to the one that resulted in the death of Lorenzo Bandini in the Monaco Grand Prix the previous year.

[1] Servoz-Gavin felt that the risks inherent in Formula One and racing in general were not worthwhile but the problems with his vision may have influenced his decision.

[4][5] After his racing career was over, Servoz-Gavin lived on a houseboat and suffered serious burns when a gas bottle exploded on his boat in 1982.
