John Paul Lyndon Regis, MBE (born 13 October 1966, Lewisham, London) is a retired English sprinter. During his career, he won gold medals in the 200 metres at the 1989 World Indoor Championships and the 1990 European Championships, and a silver medal in the distance at the 1993 World Championships.
He was a member of the British teams which won the gold medal in the 4×400 metres relay at the 1991 World Championships, and the silver medal in the 4×100 metres relay at the 1988 Olympic Games. Regis is still the British 200 metres record-holder, which he set in 1994.
Regis's most significant successes in individual events came when competing in the 200 metres. He was the first British athlete to run under 20 seconds for the distance, and still holds the UK record for the event. He was an indoor world champion and an outdoor World Championship runner-up at the distance, and also finished sixth in the event at the 1992 Olympic Games.
Regis also achieved considerable success running in relay races, winning major international medals in both the 4 x 100 metres relay and the 4 x 400 metres relay. Most notably, he ran the third leg for the British 4 × 400 m relay team at the 1991 World Championships in Tokyo, helping them defeat the heavily-favoured team from the United States and claim the gold medal. He was also a part of the British 4 × 400 m team in 1990 which set a European Championship record for the event. On 3 March 1991, Regis was a member of the British team which set the world indoor record for the rarely contested 4 x 200 metres with a time of 1:22.11, which has not yet been bettered.
