2012–13 Nemzeti Bajnokság I (women's handball)

The 2012–13 Nemzeti Bajnokság I was the sixty-second edition of the top level championship in the Hungarian team handball for women. The regular season began on 31 August 2012 and concluded on 31 March 2013, followed by the classification rounds and the playoff finals.

Defending champions Győri ETO KC won the regular season with an almost perfect performance: 21 victories on 22 games and only one draw against their rival Ferencvárosi TC, last season's runners-up. This year's final also confronted Győr to Ferencváros, after both teams had easily won their semi-finals against Váci NKSE and Érd NK. Unlike last season's final, Ferencváros did not challenge the eventual champion as Győr won both legs by six and seventeen goals and so became Hungarian champion for the tenth time.

Teams
This year, twelve teams competed in the championship: eleven clubs from the past season and only one promoted team from the second division, Budapest SE, the winner of the Eastern group. It was the first time that this club had played in the elite. As per the previous edition, the winner of the Western group, Mohácsi TE announced that they didn't want to be promoted. As a result, last season's eleventh placed Kiskunhalas NKSE escaped relegation and stayed in the first division.

The league comprised two teams from the capital Budapest (Ferencváros and BSE); two clubs from Central Hungary (Érd and Vác); two from the Southern Great Plain (Békéscsaba and Kiskunhalas); three from Central Transdanubia (Veszprém, Fehérvár, Dunaújváros) and only one team from Western Transdanubia (Győr) and the Northern Great Plain (DVSC).

As Hungarian champion, Győri Audi ETO KC entered the group phase of the EHF Champions League while EHF Cup Winners' Cup's winner FTC-Rail Cargo Hungaria also reached the Top 16 after beating IUVENTA Michalovce in the qualification round. Third and fourth placed Siófok KC and Érdi VSE played in the EHF Cup. It was the first participation in a European Cup for either team. Finally, the runner-up and the bronze medallist of the Hungarian Cup, Váci NSKE and Békéscsabai ENKSE, competed in the EHF Cup Winners' Cup.
