This is a list of butterflies of Great Britain, including extinct, naturalised species and those of dubious origin. The list comprises butterfly species listed in The Moths and Butterflies of Great Britain and Ireland by Emmet et al. and Britain's Butterflies by Tomlinson and Still.
A study by NERC in 2004 found there has been a species decline of 71% of butterfly species between 1983 and 2003. Species listed in the 2007 UK Biodiversity Action Plan (BAP) are indicated by a double-dagger symbol (‡)—two species so listed for research purposes only are also indicated with an asterisk (‡*). Range expansions according to the 2010 Atlas of Butterflies in Britain and Ireland.
