Lynn Davies CBE (born 20 May 1942) is a Welsh former track and field athlete who specialised in the long jump. He was the 1964 Olympic champion in the event.

Davies was born in Nantymoel near Bridgend and was a member of the Cardiff Amateur Athletic Club.

He was the son of Tegfryn Davies, a miner, of 14 Commercial Street. He attended Ogmore County Grammar School. He was in the 1st Ogmore Vale Scouts. He played the piano. He gained A-levels in Maths, English and History in 1960. He trained to become a teacher at Cardiff Training College.

From September 1964 he taught at Bridgend Grammar School, until October 1965.

He was a PE college lecturer at Cardiff College of Education from April 1966.

Davies, a member of Roath Harriers, won an Olympic gold medal in the long jump in 1964 with a mark of 8.07 metres (26 ft 6 in), earning himself the nickname "Lynn the Leap" and winning the first ever long jump gold medal for Great Britain.

He finished ninth in 1968, having been his nation's flag bearer at the opening ceremony. In 1964 he also competed in the 100 metres and 4×100 metres contests. On 2 November 1964 he returned to a welcome from the Garw Valley and Ogmore Valley, in a motorcade from Cardiff. He was the first Welsh person to win individual Olympic gold in a field event.

He was 18th in the 1972 Olympic long jump, his selection being something of a surprise at the time.^{[citation needed]}
