1966 Great Britain Lions tour

The 1966 Great Britain Lions tour was the Great Britain national rugby league team's 13th tour of Australasia and took place from June to August 1966. A total of 30 matches were played against local club and representative sides during the tour, including a three match Test match series against Australia and a two-game series against New Zealand.

Great Britain failed to regain The Ashes against Australia following their home defeat in 1963, but had more success on the New Zealand leg of the tour, winning all eight games.

Touring squad
The 26-man touring squad was announced on 23 March 1966, with Harry Poole named as captain, and Ken Gowers selected as vice-captain. A few days later, Alex Murphy withdrew from the squad due to business commitments, and was replaced by Ian Brooke. Murphy's withdrawal meant that Brian Edgar was the only member of the squad who had toured previously with the Lions.
