- Thessalus, son of Haemon,[1] son of Chlorus,[2] son of Pelasgus.[3]
- Thessalus, son of Poseidon and one of the reputed father of Minyas, founder of Minyan Orchomenus.[4]
- Thessalus, son of Jason and Medea, the twin of Alcimenes and older brother of Tisandrus. He escaped being murdered by his mother and, after the death of Acastus, became king of Iolcus.[5]
