British athletes have appeared in every Summer Olympic Games of the modern era, alongside Australia, France, Greece, and Switzerland, although Great Britain is the only team to have won at least one gold medal at all of them.

This streak was maintained in Paris when Rosalind Canter, Laura Collett and Tom McEwen won gold in the Equestrian Team eventing competition on Day three of the Games.

During the Games the British team won its first ever Olympic medals in sport climbing, with Toby Roberts' gold in the men's combined, and in artistic swimming, with Kate Shortman and Isabelle Thorpe taking silver in the women's duet.

England failed to do this, finishing in second place behind the Netherlands on the same points but having a lower goal scored total in their UEFA Women's Nations League 2023-24 group, therefore ending GB hopes of qualifying for the Olympics.
