The Moluccan diaspora refers to overseas Indonesians of Moluccan birth or descent living outside Indonesia. The most significant Moluccan diaspora community lives in the Netherlands, where it numbers c. 70,000 people as of 2018.

Moluccans are the Austronesian-speaking and Papuan-speaking ethnic groups indigenous to the Maluku Islands, Eastern Indonesia. The region was historically known as the Spice Islands, and today consists of two Indonesian provinces of Maluku and North Maluku. As such, "Moluccans" is used as a blanket term for the various ethnic and linguistic groups native to the islands.
