Ronon Dex is a fictional character in the 2004 science fiction television series Stargate Atlantis. Played by Jason Momoa. The storyline is about Ronon who is from Sateda. Sateda is a civilization which was at a technological level comparable to Earth in the mid-20th century before it was devastated by the Wraith alongside all other advanced civilizations in the Pegasus galaxy. When Ronon Dex and the Atlantis expedition first met in the season 2 episode "Runner", Ronon Dex had been a Runner for the past seven years. He joined the Atlantis Expedition shortly afterward, effectively replacing Aiden Ford on Sheppard's team after Ford had become addicted to a Wraith enzyme and had fled Atlantis.

Jason Momoa, along with some of his fellow cast members, said that they think of Ronon as the Atlantis version of Chewbacca.^[1] This joke was also carried through into the show, as Lt Col Sheppard occasionally refers to Ronon as "Chewy."^[2]
