LazyTown (Icelandic: Latibær) is an English-language Icelandic children's educational musical television series created by aerobics champion Magnús Scheving. Originally produced in English, it has been broadcast in dozens of languages globally. Designed to encourage healthy lifestyles, the series was based on Scheving's stage play Áfram Latibær!, itself adapted from a book that Scheving wrote in 1995.

The series was commissioned by Nickelodeon in early 2003, following the production of two stage plays and a test pilot. Originally performed in English, it was later dubbed into thirty languages and broadcast in over 180 countries. It combines live action, puppetry and computer animation, making it one of the most expensive children's shows, with the cost per episode being over five times that of the average children’s show.

The first two seasons, consisting of fifty-two episodes, were produced from 2004 to 2007. LazyTown originally aired on Nickelodeon's Nick Jr. block in the United States and the United Kingdom and RÚV in Iceland. In 2011, Turner Broadcasting System Europe acquired LazyTown Entertainment and commissioned the third and fourth seasons. Consisting of twenty-six episodes, they premiered in 2013 on Turner's Cartoonito and later on Viacom's Channel 5, for a total of seventy-eight episodes and four seasons.

Multiple spin-offs were created, including stage productions and LazyTown Extra, a short-form series for younger children.
