The 2001–02 Nemzeti Bajnokság I, also known as NB I, was the 100th season of top-tier football in Hungary.
The league was officially named Borsodi Liga for sponsoring reasons.
It was contested by 12 teams, and Zalaegerszegi TE won the championship for the first time in their history.
Zalaegerszeg, guided by coach Péter Bozsik, only lost two home games throughout the campaign.
ZTE's status as champions was confirmed in the 37th round, after a 1-1 draw against Ferencváros meant that Zalaegerszeg's 5 point lead over FTC was impossible to overcome.
