Vasileios Petimezas or Petmezas (Greek, Modern (1453-);: Βασίλειος Πετ[ι]μεζάς, c. 1785–1872) was a Greek revolutionary leader during the Greek War of Independence, politician and general.
Vasileios Petimezas was born in about 1785 as the son of Athanasios Petimezas. He hailed from the important clan of the Petimezas or Petmezas from the village of Soudena, near Kalavryta.
After his father was murdered in 1804 he fled to British-held Zakynthos, and enrolled in the British-sponsored Greek light infantry units there, along with his brother Nikolaos.
He returned to the Peloponnese at the outbreak of the Greek War of Independence, and fought in several battles at Kalavryta, Levidi, Corinth, Argos, Akrata, and Trikorfa, as well as the campaign against Mustafa Pasha Bushatli. In 1826, with 600 men, he and his brother NIkolaos occupied Mega Spilaio and drove back the attacks of Ibrahim Pasha of Egypt.
He was elected representative to the Greek national assemblies, and later as MP to the Hellenic Parliament.
He reached the rank of lieutenant general.
He died in 1872.
