Six Flags St. Louis opened in 1971 as Six Flags Over Mid-America. It has been a summer institution in this region for 55 years. In March 2026, Six Flags Entertainment Corporation sold it — along with six other parks — to a real estate investment trust called EPR Properties for $342 million. A Florida-based company called Enchanted Parks will operate it starting next season.

The new name: Mid-America by Enchanted Parks.

The internet noticed immediately that “mid” in current usage means mediocre, disappointing, of below-average quality. Reddit did not let this pass quietly. “People are going to call it Mid-America because it’s mid,” read one of the kinder assessments. Others noted the full name — Mid-America by Enchanted Parks — has an unusual number of syllables for something you’d say to a child excited about a roller coaster.

The CEO of Enchanted Parks, James Harhi, described Six Flags St. Louis as the “crown jewel” of his company’s portfolio. He said the park wasn’t originally included in the deal but that he pushed to have it added. That’s an encouraging sign — it suggests someone actually wants the thing rather than just acquired it by accident.

The park keeps its Six Flags branding through the end of 2026. Season passes are honored. The rides are the same. The Looney Tunes characters are still there, for now, though the new ownership is in talks with Warner Bros. about what happens to those licenses next year.

It opened as Six Flags Over Mid-America. It’s becoming Mid-America by Enchanted Parks. Somewhere in that arc is the entire story of how things get named, renamed, sold, and eventually called something nobody asked for.
