Zein Pun (Burmese: ဇိတ်ပွန် Burmese pronunciation: [zeɪʔ pʊ̀ɰ̃]; 1295–1330) was king of Martaban for one week in 1330. Of commoner background, Zein Pun rose from a childhood servant of Prince Saw Zein to a powerful commander during Saw Zein's reign. The ambitious commander then staged a coup against his lord, killing the king. But the usurper himself was killed a week later in a counter-coup organized by Queen Sanda Min Hla.
