Michael of Zahumlje, also known as Michael Višević (Croatian/Bosnian/Serbian: Mihajlo Višević, Cyrillic: Михаило Вишевић) or rarely as Michael Vuševukčić, was an independent Slavic ruler of Zahumlje, in present-day western Herzegovina and southern Croatia, who flourished in the early part of the 10th century. A neighbour of the Kingdom of Croatia and Serbia as well as an ally of Bulgaria, he was nevertheless able to maintain independent rule throughout at least a good part of his reign.
