Lego Ben 10, was a Lego theme based on the animated television series Ben 10: Alien Force. There were the total of six sets of buildable figures similar to Bionicle. The line had only lasted one wave before being discontinued. It was thought to be the replacement for Bionicle, but the replacement is actually Hero Factory.

Ben 10 is an acclaimed American media franchise created by "Man of Action" (a group consisting of Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle), and produced by Cartoon Network Studios. The franchise is about a boy who acquires a watch-like alien device called the Omnitrix (later the Ultimatrix) attached to his wrist that allows him to turn into alien creatures. In April 2008, Ben 10 (the original television series) was succeeded by Ben 10: Alien Force, which itself was succeeded in April 2010 by Ben 10: Ultimate Alien, which will be succeeded by Ben 10: Omniverse in June 2012 in the US and on September 2012 in other countries. The theme song for the first series was written by Andy Sturmer and sung by Moxy. The theme songs for both of the sequel series were instrumental. Reruns of previously aired episodes are currently being aired on Cartoon Network and its fellow television channel, Boomerang.

The Ben 10 franchise has grossed over $2 billion in retail sales in Europe, the Middle East and Africa (EMEA) and has sold 100 million toys worldwide.
