Winx Club (Polish)

Initially produced by Start International Polska, this dub was originally created and used for airings of seasons 3, 5-7 and the four one-hour specials on Nickelodeon in ; for season 4, the channel acquired the dub of the original run that had aired on ZigZap. Season 3 of this dub is based on Cinélume's English version instead of Atlas Oceanic's English version, due to Nickelodeon US commissioning international dubs of Seasons 3 and 4 before they finished their own English version for distribution. The dub's run on Nickelodeon concluded on January 13, 2016, with the end of the seventh season.

Production of the dub moved to Studio Sonica — which had previously dubbed the fourth season, albeit with a completely different cast — for the eighth season, with the series moving back to TeleTOON+ due to Nick having little involvement in the season, broadcasting in 2020. The title of the dub was changed for that season to the translated name Klub Winx, which had previously been used for the dub of the original run.

Broadcast
The dub initially premiered on Nickelodeon Central & Eastern Europe on 16 October 2011, with the first one-hour special, The Fate of Bloom. After Nickelodeon Poland was re-split from the feed in 2012, the dub moved to the separate Nickelodeon channel for Poland, but it continued to air on Nickelodeon Central & Eastern Europe until 2017 due to Poland receiving only a separate SD channel, while continuing to receive the Central & Eastern European version of the HD channel. The dub's run on Nickelodeon finished on 13 January 2016 with the end of season 7, as season 8 did not air on the channel.

Season 8 aired on TeleTOON+ throughout 2020, where the original run of the series first aired, due to Nickelodeon having little involvement in the production of the season. It concluded on 12 May 2020.
