Lego Ninjago

Lego Ninjago is a Lego theme that was created in 2011 and a flagship brand of The Lego Group. It is the first theme to be based on ninja since the discontinuation of the Lego Ninja theme in 2000. It was produced to coincide with the computer-animated television series Ninjago, which was superseded in 2023 by a new series titled Ninjago: Dragons Rising.

The theme originally focused on a group of six teenage ninja, led by the legendary Green Ninja, Lloyd Garmadon. The ninja characters are "Elemental Masters", which means that they each possess elemental powers. They are also trained in the fictional martial art of "Spinjitzu" by their ancient and wise teacher, Master Wu, giving them the ability to fight against the forces of evil. In 2023, new characters were introduced for the replacement series.

Ninjago enjoyed phenomenal popularity and success in its first year, and a further two years were commissioned before a planned discontinuation in 2013. However, after a brief hiatus, the line was continued after feedback from fans and has been in production ever since. The Lego Group developed the theme into a media franchise aimed primarily at young boys and pre-teenage boys, which has produced books, video games and theme park attractions. The popularity of the TV series and the toy line resulted in the production of The Lego Ninjago Movie, released in 2017, which was the third film in The Lego Movie franchise. On January 14, 2021, the Ninjago theme celebrated its tenth anniversary, making it one of The Lego Group's longest-running and most successful original brands.
