Bionnus or Bionnos (Ancient Greek: Βίωννος) was a town and polis (city-state)[1] of ancient Crete.
It is known by epigraphic evidence.
In a list of theorodokoi of Delphi from 230–210 BCE, Bionnus is mentioned between Psycheion and Matala.
[1][2] The site of Bionnus is located near modern Pyrgos ('high ground'), about 2 kilometres (1.2 mi) south of Kerames.
