The Aeon Cup (stylized as ÆON CUP; Japanese: イオンカップ), also known as the Worldwide Rhythmic Gymnastics Club Championships (世界新体操クラブ選手権), is an international rhythmic gymnastics competition hosted by the Japanese Rhythmic Gymnastics Federation.
The event was founded in 1994 and takes its name from its sponsor, Aeon Co., Ltd. The president of Aeon (then JUSCO) at the time proposed the event to promote "peace through sports". Athletes from both Serbia and Bosnia shook hands with each other during the inaugural event despite the ongoing Yugoslav Wars.
The event paused for two years due to the COVID-19 pandemic.
The Aeon Cup is contested between rhythmic gymnastics clubs from different countries. No flags or national anthems are featured. Japan enters two clubs.
Each team includes two senior and one junior gymnasts. In addition to a club title, two all-around titles (a senior and a junior) are awarded.
A portion of the event's proceeds are donated to the United Nations High Commissioner for Refugees.
The tournament is held annually at the Tokyo Metropolitan Gymnasium.
