Petros Cassadine was a fictional character on the ABC soap opera, General Hospital.

He was portrayed by actor John Colicosin from 1984-1985.


Petros came to town in 1984 as the cousin of Mikkos Cassadine, Tony Cassadine, Victor Cassadine, Sophia Cassadine-Davidovitch, and Dimitri Cassadine. He looked identical to Mikkos. While in town he visited General Hospital to monitor how the Cassadine money was being spent.

He also interacted with Robert Scorpio and Sean Donely while trying to acquire a spy ship called, The Venture. Petros was enraged when Sean and Robert, both spies with the World Security Bureau, blocked his purchase of the ship and left town vowing vengeance on them both.

Later, it is revealed that Petros died.
