Ninjago: Masters of Spinjitzu

Ninjago: Masters of Spinjitzu is a Danish-Canadian2 3D animated television series produced by Wil Film ApS and The Lego Group, both headquarted in Denmark. It was created to coincide with the Lego Ninjago line of construction toys, many of which are based on elements of the series. It centers on the fictional world of Ninjago, telling the story of a group of young Ninja and their battles against the forces of evil.

Ninjago began with two pilot episodes in January 2011, which were followed by two 13-episode seasons that aired from January to November 2012. Both the Lego theme and the series had an intended shelf life of three years, so the second season was originally intended to be the last. However, continued success of the series and its product line led to ten seasons being produced in total. In the eighth season, several character designs and aesthetics were borrowed from the theatrical film The Lego Ninjago Movie, which was released in 2017.

The series was created by Michael Hegner and Tommy Andreasen, two Danish film producers. The series' animation is directed at Wil Film ApS in Copenhagen, and the English-language voice cast is recorded in Canada. In Denmark, where the series' main production companies are located, Ninjago premiered on Nickelodeon. It airs on various Nickelodeon networks internationally and on Cartoon Network in the United States and United Kingdom. In Canada, the series airs on YTV.
