There are 4 Six Flags parks in California. Two of them are full Six Flags theme parks:

Additionally, after a recent merger of Six Flags with Cedar Fair, there are four listed parks in California connected to these companies, including the above Six Flags parks along with Knott's Berry Farm (owned by Cedar Fair) and California's Great America, which is expected to close by 2033.
