Who voices King Julien in the Madagascar movies?

Sacha Baron Cohen voices King Julien in the Madagascar movies.

King Julien XIII is a ring-tailed lemur and the self-proclaimed ruler of the lemurs encountered by Alex and his friends. He is flamboyant, impulsive and intensely interested in dancing and entertainment. Cohen’s vocal performance helped make Julien one of the franchise’s most recognizable supporting characters.

The character first appears in Madagascar, where the lemurs live near the stranded zoo animals. Julien’s comic confidence contrasts with Maurice’s caution and Mort’s wide-eyed devotion. The character became important enough to lead later television productions, including All Hail King Julien.

A common mix-up is identifying Julien as a fictional version of a different lemur species. The character is specifically a ring-tailed lemur, a real Madagascar species known for its striped tail. His famous dance-focused personality, however, is a comedic invention of the films.
