Yes, Kings Island (located in Mason, Ohio) and Kings Dominion (located in Doswell, Virginia) are sister parks with a shared corporate history. Both were originally developed by Family Leisure Centers, a joint venture between Taft Broadcasting Company and Top Value Enterprises. Kings Island opened first in 1972, and because of its massive success, Kings Dominion was built as a "twin" park, opening its gates in 1975. This shared DNA is why both parks feature an iconic one-third scale replica of the Eiffel Tower as their central landmark and originally had nearly identical layouts and themed areas like "International Street." Both parks passed through the ownership of Paramount Communications in the 1990s (becoming "Paramount Parks") before being acquired by Cedar Fair Entertainment Company in 2006. In 2024, Cedar Fair merged with Six Flags, meaning both parks are now part of the Six Flags Entertainment Corporation portfolio, continuing their long-standing relationship as two of the premier regional theme parks in the United States.
Yes, Kings Island and Kings Dominion are related—they are both amusement parks owned and operated by Cedar Fair Entertainment Company.
So while they share corporate ownership and some historical ties, each park has its own distinct identity and ride lineup.
