M2 (MTV kettő) is a Hungarian television channel owned and operated by Duna Média since 2015.

On 22 December 2012, M2's daytime hours became dedicated to children's programming.

Similar to TVP ABC in Poland, CBeebies, CBBC and BBC Three in the UK, M2 broadcasts children's programming during the day while M2 Petőfi targets youth audiences as they broadcast at night with music videos (local and abroad), music-related (music concerts) and youth-related programming, as well as exclusive content from its radio counterpart, Petőfi Rádió.

On 3 November 2021, M2 Petőfi, the prime-time adult block, will be rebranded for the first time since 2015.

The rebranding will reflect as well as M2, the main children channel that the new look debuted on 1 October 2020.
