Great Britain was able to submit a squad of two synchronized swimmers to compete only in the women's duet, after picking up one of four spare berths freed by the continental selection for being the next highest ranking nation at the FINA Olympic test event in Rio de Janeiro. Katie Clark and Olivia Federici, who were both part of the Great Britain lineup for the team event at the 2012 Games, were confirmed as the British representatives in May 2016.
