The club was founded on 29 January 1983, upon the remnants of the previously well-known and successful club Highlands Park, which Sono opted to buy when he ended his playing career in the United States. The club was named Dion Cosmos in its initial 1983 season, with the first part of the name representing the previous sponsor of Highlands Park and the second part being the fingerprint of Jomo Sono, who decided to name his newly bought club after his former NASL club, the New York Cosmos. Since 1984, the name of the club has been Jomo Cosmos.
“Firstly I would like to wish Jomo Cosmos Happy Birthday, its been 32 years of amazing football. It has been a long journey with lots of happy and sad memories, ones that i will always treasure. This club is very close to my heart. I would like the past, present and present member to celebrate this very special moment with us.”
