Basketball was only included from the 8th edition of the Island Games at Gotland 1999. It has become a regular fixture in the sporting line up since then, only being missed out for the Shetland 2005 Games. Ynys Môn have only sent teams to 4 different Games. The team returned for the Guernsey 2023 Games after a 16 year absence.

The best performances came at Guernsey 2003 where both the men’s and Women’s teams finished 6th in their respective tournaments. The other two appearances from the Men’s side have seen them place 8th each time.
