Iain Robert Balshaw, MBE (born 18 April 1979) is an English former rugby union player who played on the wing or at full back for Bath, Leeds Carnegie, Gloucester and Biarritz Olympique.

Balshaw was out of action for the beginning of the season with a groin injury, but after three months of work with the Leeds medical staff he was back to fitness.

After a run of five impressive starts Balshaw was rewarded with the captaincy for the Powergen Cup semi-final game against London Irish, and this performance saw him gain a recall to the England squad.

The 2002/2003 season saw him as a member of the England squad for the tour of New Zealand and Australia, before joining the party for Churchill Cup matches in North America.

He scored two tries in a 'non-cap' international against Japan in Tokyo in June 2002, having recovered from shoulder surgery that restricted him to nine games in the previous eleven months for Bath.

Problems with injury meant that his subsequent international appearances were few, despite criticism Clive Woodward retained faith in his ability and selected him in the 2003 World Cup squad.

Balshaw played in the warm-up match against France in Marseille and impressed in England's World Cup game against Samoa, when he caught a diagonal kick from Jonny Wilkinson to score a crucial try in the 70th minute.
