This article chronicles the history of the depiction of Lego building toys in media franchising with emphasis on film and television co-produced by owner The Lego Group.

Brickfilms (films using Lego) have existed since the 1970s. In 2003, Lego officially made its first partnership to make films based on its toy property. They chose Bionicle as the property and they made a deal with Miramax to make a trilogy of Bionicle films. After the trilogy ended, a new trilogy based on Bionicle was planned with Universal after the Miramax film contract ended and the first film in the new trilogy would be titled Bionicle: The Legend Reborn, but plans broke down between Lego and Universal, resulting in the fifth film being cancelled. Another film was later released, entitled Lego: The Adventures of Clutch Powers. The film received positive reviews from fans and critics and, after the DVD release, a sequel was set to star Clutch as the hero again. A short film based on Clutch Powers was later released but a full sequel never materialized.

In the summer of 2009, Lego made a deal with Warner Bros. Pictures to make a film based on the property. In the same year, Lego also planned the concept for the now successful theme Lego Ninjago. In 2011, Lego released a TV series titled Lego Ninjago: Masters of Spinjitzu and Ninjago series achieved popularity. A video game based on the show was later released and the show reached its planned conclusion after a two-year run.

A new show titled Legends of Chima aired in January 2013 and was intended to be Ninjago's successor. The show received mixed reviews, however, with Lego fans instead demanding the return of Ninjago. Lego revived Ninjago: Masters of Spinjitzu in 2014 with a new season and continued to release 1–2 seasons every year. Initially titled "Lego: The Piece of Resistance", the film was later renamed The Lego Movie by Warner Bros. and was released in February 2014. Due to the success of the film, its sequel, The Lego Movie 2: The Second Part, was released five years later, while its spin-offs, The Lego Batman Movie and The Lego Ninjago Movie, were released in 2017. The Lego Ninjago Movie is not connected to the events shown in the television show.

In 2014, Mixels also debuted. In late 2015, Nexo Knights was introduced, replacing Legends of Chima.

In late 2016, Ninjago released a Halloween TV special for its fifth anniversary.

An additional film with Warner Bros named Billion Brick Race was planned, but cancelled in 2018 for unknown reasons. Little is known about what the film was supposed to be, with the exception of some concept artwork shared by director Jorge Gutierrez.

In March 2019, Ninjago released an 88-minute TV movie called March of the Oni on Cartoon Network, which also celebrated the 100th episode of the show. The show reached its 11th year of airing having released season 15 in 2022.

By April 2020, Universal Pictures established a five-year deal for exclusive rights for the production of further Lego films with The Lego Group; the four existing Lego films made by Warner Bros. (The Lego Movie, The Lego Movie 2, The Lego Batman Movie, and The Lego Ninjago Movie) would stay with that studio. This move potentially allows Universal to make Lego films based on its own catalog of properties such as Jurassic Park, Fast & Furious, Despicable Me, Shrek, and Back To The Future.^[1][2][3]

In January 2024, it was announced that Pharrell Williams is making an animated biographical film of his career in Lego form. It is set to be released in October 2024 by Focus Features.^[4]
