Great Britain competed at the 2008 Summer Paralympics in Beijing, People's Republic of China. Great Britain sent a delegation of around 400, of which 212 were athletes, to compete in eighteen sports at the Games. The team was made up of athletes from the whole United Kingdom; athletes from Northern Ireland, who may elect to hold Irish citizenship under the pre-1999 article 2 of the Irish constitution, are able to be selected to represent either Great Britain or Ireland at the Paralympics. Additionally some British overseas territories compete separately from Britain in Paralympic competition.
