The International Camellia Society (ICS) is a non-profit organization devoted to the genus Camellia, founded in April 1962.

One of its most important achievements is the International Camellia Register, which lists the tens of thousands of Camellia cultivars registered and can be consulted free of charge on-line by anyone.

The Benelux department of the association was founded in 2002. The department has approximately 100 members, mainly in Belgium and the Netherlands.
