The Boss is a wooden roller coaster located in the Britannia section of Six Flags St. Louis in Eureka, Missouri.

The new ride would be named The Boss and be a large terrain wooden roller coaster, very similar to The Beast at Kings Island.

It would cover 12 acres (4.9 ha) of land on the northwest edge of the property, crossing over itself six times and ending with a 560-degree helix.

During the ride's winter rehab prior to the start of the 2018 season, the 570° helix was removed and replaced with a 180 degree banked turn, shortening the coaster by 420 feet (130 m).

Following this, the track makes a right turn, passes under the lift hill, and over a pair of smaller airtime hills with slight right turns, before making a 180 degree banked turnaround (570 degree double helix prior to 2018), leading into a bunny hop and the final brake run.
