Zainal Abidin ; born Tidore Wonge or Gapi Buta ) was the 18th or 19th ruler of the Ternate Sultanate of Maluku, located in modern-day Indonesia. His life is only described in sources dating from the 16th century or later. According to these sources he was the first ruler of Ternate to use the title Sultan rather than Kolano, or king, and enacted a number of changes in the government, based on Islamic Law, technically transforming Ternate into an Islamic kingdom.

The Sultanate of Ternate, previously also known as the Kingdom of Gapi is one of the oldest Muslim kingdoms in Indonesia besides the sultanates of Tidore, Jailolo, and Bacan.
