Ellen May 'Elly' Gandy is an Australian female butterfly swimmer originally from Great Britain. She represented Great Britain at the 2008 Summer Olympics and 2012 Summer Olympics in the 200m butterfly swimming event, and was the 2011 World silver medalist at that distance. Following a disappointing 2012 Games, Gandy expressed an intention to swim for Australia, having lived and trained there since 2007, and served a period of ineligibility in order to do so. She represented Australia for the first time at a FINA World Cup event in Eindhoven in August 2013. Since her switch, Gandy has publicly adopted the first name Elly, the name by which she has been known privately in Australia. Under her new flag, Gandy is the current holder of the Australian and Commonwealth short-course 200m butterfly record. She remains the British long course record-holder in 100 and 200 metre butterfly, and 4 x 100 metre medley.
