Sea Dragon is a junior wooden roller coaster located at the Columbus Zoo and Aquarium in Powell, Ohio.

It was one of three junior wooden coasters that Allen designed shortly after becoming president of PTC in 1954 – the other two were Flyer at Hunt's Pier and Valley Volcano at Angela Park.

They were based on earlier designs developed by another legendary coaster architect Herbert Schmeck, who was Allen's mentor.

[3][4] Following the closure of Big Dipper in 2007, the Sea Dragon became the oldest operating wooden roller coaster in Ohio.
