English Dubs

Winx Club has had two separate runs. The first run was the original series (first four seasons), which was produced from 2004 to 2009 by the Rainbow animation studio in Italy, before Viacom became a co-owner of the studio. After Viacom (owner of Nickelodeon) started managing Rainbow, it began production on a revival series, which was jointly produced between Italy and the United States (at Nickelodeon Animation Studio). The revival began in 2011 with four specials, which retell the story of the original first and second seasons.

Because the second run (seasons 5 onward) of Winx Club was co-produced in the United States, Viacom/Nickelodeon maintained only one English voice cast at all times for the episodes. Rainbow and Viacom directly oversaw these English dubs as well. During the original run (before Viacom produced the show), Rainbow did not oversee the English dubs and they were not a priority. Rainbow exported the original seasons to third-party companies, resulting in multiple separate English dubs being made for seasons 1 - 3.

Below is a guide to the dubs for both the original series and Viacom's revival. At the end is a viewing order for every season and movie.

Original series

 * Cinélume dubbed the entire original series (Seasons 1 - 4) in English.
 * 4Licensing Corporation dubbed Seasons 1 - 3, before their license was permanently revoked.

Viacom revival
In 2011, Viacom (owner of Nickelodeon) became a co-owner of the Rainbow studio. Together with Viacom's Nickelodeon Animation Studio, Viacom Italy produced a revived series, in which the Winx are students at Alfea again. After the financial failure of Rainbow's film Gladiators of Rome, Rainbow/Viacom cut costs on Winx Club. As a result, Viacom decided to replace the expensive Atlas Oceanic studio. Viacom chose DuArt, a studio located next to Viacom's headquarters in New York.
 * Atlas Oceanic, a Hollywood recording studio, was commissioned to dub the Specials and Seasons 5 - 6. It was the first English studio commissioned by Nickelodeon, with DuArt being the second.
 * Atlas Oceanic also re-recorded Seasons 3 - 4, so that reruns would match the voices of the revived show.
 * DuArt was commissioned by Nickelodeon to dub Season 7, which aired on Nick Jr. in the United States. DuArt's successor studio, 3Beep, dubbed Season 8. DuArt's dub is the second English dub commissioned by Nickelodeon/Viacom, after Atlas Oceanic.

Movies

 * Dubbing Brothers dubbed all three movies: The Secret of the Lost Kingdom, Magical Adventure, and The Mystery of the Abyss.
 * Atlas Oceanic dubbed the first two movies, so that reruns would match the voices of the revived show.
