Kaamatan is the Malaysian harvest festival celebrated by the Kadazan-Dusun people of Sabah.
The festival is associated with the completion of the rice harvest and is traditionally linked to indigenous Kadazan-Dusun beliefs about rice, including the legendary figure Huminodun. Modern celebrations emphasize gratitude, cultural identity, music, dancing, traditional foods, and the presentation of the Unduk Ngadau beauty pageant.
Kaamatan is generally observed throughout May and reaches its state-level climax on May 30 and 31. The final day, May 31, is commonly recognized as the main public holiday in Sabah, although local communities may hold events across a longer period.
Kaamatan is sometimes confused with Gawai Dayak, another major harvest festival in Malaysia. Gawai Dayak is primarily associated with Dayak communities in Sarawak, while Kaamatan is especially associated with Sabah’s Kadazan-Dusun communities.
