Edwards won his first international cap for Wales on 1 April 1967 at the age of 19 against France in Paris.
Wales lost 20–14 to eventual championship winners France.
Between 1967 and 1978 Edwards won 53 caps for Wales, including 13 as captain.
All his caps were won in succession; he never had a dip in form or an injury that would allow anybody else to take his place.
He scored twenty tries in internationals.

Edwards is Wales's youngest ever captain, first taking the captaincy at the age of 20 in February 1968 against Scotland – a game which the Welsh side won 5–0.
Edwards was very fortunate in playing with two of the best outside halves the game has ever seen: Barry John and Phil Bennett.
In the early part of his career, Edwards and his club team mate Barry John appeared inseparable, always knowing what the other was doing.
During his era the Welsh side dominated the Five Nations Championship, winning the title seven times, including three grand slams.
In 1969, Edwards was named Player of the Year in Wales.

In 1974 Edwards was named BBC Wales Sports Personality of the year.
He followed up this success by receiving an MBE in 1975.

He was the subject of This Is Your Life in 1976 when he was surprised by Eamonn Andrews.

Edwards' long successful international career came to an end on 18 March 1978 in the same way as he had started his career – against France in the Five Nations Championship.
However, unlike on his debut, Edwards celebrated with a 16–7 winning finish in front of a home crowd at the Arms Park in Cardiff.
Wales also sealed the Grand Slam and a third consecutive Triple Crown – a record, given that no team had ever won it more than twice in a row.
To crown his achievements he was named Rothmans Player of the Year 1978.
