This is a list of the longest animated feature films with a running time of 120 minutes (2 hours) or more are included here. While the majority of animated features on this list are produced in Japan or the United States, some animated features are also produced outside of those countries.
This list excludes some individual animated features for which traditional narrative techniques are not applicable, or that were not intended for wide release. The longest films in experimental form are typically longer than those given a wide release.
<blockquote>NOTE: Some releases are extended cuts or director's cuts and are ranked according to the longest verified running time. </blockquote>
This section lists films conceived as an artistic unity and produced simultaneously, or consecutively with no significant interruption or change of production team, despite being released with separate premieres.
