1/38 Evzone Regiment Ioannis Velissariou (Greek: Ιωάννης Βελισσαρίου, 26 November 1861 – 13 July 1913) was a Hellenic Army officer and hero of the Balkan Wars.

He acquired his first combat experience during the Greco-Turkish War of 1897, where he distinguished himself at the battles of Melouna and Derven-Fourkas, covering the Greek positions.

At the Battle of Sarantaporo he managed to advance rapidly with his unit against the Ottoman forces and cut their withdrawal, causing general unrest to the enemy.

On February 19, 1913, the Greek headquarters ordered a general attack against the Ottoman fortifications in Bizani, which covered the city of Ioannina.

[3] The Evzone battalions of Velissariou and Georgios Iatridis penetrated rapidly north and managed to cut off the only escape route of the enemy troops with the capture of the village of Agios Ioannis, between Bizani and Ioannina.
