Louise Dunn Aitken-Walker MBE (born January 1960 in Duns, Berwickshire) is a British rally and racing driver. Aitken-Walker entered competition in 1979 and finished 19th in her first Rally GB two years later. She contested the 1989 British Touring Car Championship in a Class C Vauxhall Astra finishing fifth in points, and in 1990 was the first ever Ladies World Champion, the pinnacle of a successful 14-year career. She was awarded the Segrave Trophy in 1990. She retired in 1993 to have a family (son John and daughter Gina) and concentrate on her business affairs. She runs Aitken-Walker Cars, which specializes in quality used cars, with her husband Graham in the Scottish Borders. In September 2008, Aitken-Walker took part in the Colin McRae Forest Stages Rally, a round of the Scottish Rally Championship centred in Perth in Scotland. A historic Talbot Sunbeam Lotus was her chosen car for the event. She was one of a number of ex-world and British champions to take part in the event in memory of McRae, who died in 2007. Aitken-Walker was inducted into the Scottish Sports Hall of Fame in 2002.
