What is an OA Convention?

Conventions are special OA events, typically held annually. The purpose of an OA convention is to encourage unity within a region (if it is a regional convention), or to encourage unity throughout OA, and to raise funds for carrying the message of recovery to those who suffer with our common disease of compulsive eating.

The World Service Convention is a recovery event open to all OA members worldwide. This convention is held every five years to promote recovery, fun, and fellowship in Overeaters Anonymous. You can attend workshops, marathons, and other OA-related events, and hear speakers from other countries. Come share your experience, strength, and hope with hundreds of OA members from around the world.

The World Service Business Conference is April 20-25, 2026. In- person attendance only! The theme is: “The OA Solution is for Life.” For details, please click here.
