Ioannis Miaoulis

Ioannis Miaoulis (Greek: Ιωάννης Μιαούλης) (1803–1830) was a Greek naval officer. He was the third son of Andreas Miaoulis, a revolutionary leader and a member of the Miaoulis family from Hydra.

He was born in Hydra. During the Greek War of Independence, he commanded a ship in the squadron of vice-admiral Georgios Sachtouris and distinguished himself in a naval battle between Kythira and Crete. Later, he moved to Athens, where the Acropolis was still held by an Ottoman garrison. There he was infected by typhoid fever and died in 1830 at the age of 27.
