LazyTown (Icelandic: Latibær) is an English-language Icelandic preschool children's educational television series created by aerobics champion Magnús Scheving. The show was designed to encourage healthy lifestyles. The series was based on Scheving's stage plays Áfram Latibær! (itself adapted from a book that Scheving wrote in 1991).

The series was commissioned by Nickelodeon in early 2003, following the production of two stage plays and a test pilot. It was originally performed in English; however, the show has been dubbed into more than thirty languages (including Icelandic) and broadcast in over 180 countries. The show combines live action, puppetry and computer animation, making it one of the most expensive children's shows ever made, with a cost per episode of over five times that of the average children’s show.

The first two seasons (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. Turner Broadcasting System Europe acquired LazyTown Entertainment in 2011 and commissioned the third and fourth seasons for a total of 26 new episodes, which premiered in 2013 on Turner's Cartoonito and later on Viacom's Channel 5.

Multiple spin-offs were created, including stage productions and a short-format television programme for younger children titled LazyTown Extra.
