Sprocket Rockets is a junior roller coaster at Six Flags Great America in Gurnee, Illinois, themed to a rocket trip into space. Built by Vekoma, it opened in 1998 as Spacely's Sprocket Rockets, one of the rides of the new Camp Cartoon Network children's area in Yukon Territory, and it has carried its shorter name since 2018.

The ride is a Vekoma Junior Coaster of the 207-meter model, designed by Peter Clerx. According to RCDB, a booster-wheel lift takes the single train of eight two-seat cars to about 28 feet, and the 679-foot course of hills, dips and curved turns reaches about 22 mph in a ride of about 44 seconds.

Most of the Camp Cartoon area around it, including the Crazy Bus and Yahoo River rides, was removed in early 2026, but Sprocket Rockets was left standing. The park lists a minimum height of 42 inches, or 36 inches with a companion.
