*Ninjago (previously known as Ninjago: Masters of Spinjitzu until 2019) is an animated epic-fantasy superhero television series produced by The Lego Group. It was created to coincide with the Lego Ninjago line of construction toys, which is based on the characters and events of the series. It centers on the fictional world of Ninjago, telling the story of a group of six teenage ninja and their battles against the forces of evil.

The series began with the ninja team being formed and trained by their ancient master Sensei Wu in the fictional martial art of "Spinjitzu", which is the main fighting method depicted in the show. The ninjas' base is a flying junk ship named "Destiny's Bounty", which has varied in design over the course of the series. The pilot episodes introduced the original four ninja characters named Kai, Cole, Jay and Zane and Kai's sister Nya, while the central character Lloyd Garmadon was introduced in the first season, titled Rise of the Snakes.

The series incorporates a detailed fictional lore, which is woven into the storyline using character dialogue and flashbacks. The lore mainly focuses on the history of the First Spinjitzu Master and his creation of the island of Ninjago*
