In Greek mythology, Tenes or Tennes was the eponymous hero of the island of Tenedos. He was the son either of Apollo or of King Cycnus of Colonae by Proclia, daughter or granddaughter of Laomedon. Cycnus's second wife Philonome, daughter of Tragasus or Cragasus, falsely accused Tenes of rape, bringing in a flutist named Eumolpus as witness. Cycnus believed the accusations and tried to kill Tenes and his sister Hemithea by placing them both in a chest, which was set into the ocean. However, the chest landed at the island of Leucophrye, which was later renamed Tenedos, and the two survived. The natives of the island pronounced Tenes their king. Cycnus later learned the truth, killed Eumolpus, buried Philonome alive and tried to reconcile with his children, but Tenes rejected his overture: when Cycnus's ship landed at Tenedos, Tenes took an axe and cut the moorings.
