Yes, as of 2026, Kings Dominion is officially part of the Six Flags Entertainment Corporation. This is the result of a massive "merger of equals" completed in July 2024 between the former Six Flags and Cedar Fair (the previous owner of Kings Dominion). While the park has retained its legacy branding and name, it now operates under the combined Six Flags umbrella, which is the largest regional theme park operator in North America. For guests, this merger has introduced the "All Park Passport" and a unified 2026 Season Pass system that allows unlimited access to over 40 parks across the U.S., Canada, and Mexico. This means a Kings Dominion passholder can now enjoy benefits at legacy Six Flags parks like Great Adventure or Magic Mountain, reflecting a new era of "Passport to Fun" for theme park enthusiasts.
