The 2007–08 Nemzeti Bajnokság I, also known as NB I, was the 106th season of top-tier football in Hungary. The league was officially named Soproni Liga for sponsoring reasons. The season started on 20 July 2007 and ended on 2 June 2008.
The league was contested by 16 teams and MTK Budapest emerged victorious, breaking DVSC's hegemony in the league. The two teams were in a two-way title race for much of the season, with the fate of the championship being decided on the penultimate day of the season, after MTK beat REAC 1-4 in Zugló. Debrecen finished 2nd, 2 points off the trophy. Despite failing to retain their championship, Debrecen still had a memorable season, only losing at home to champions MTK, and winning 8 of their last 9 games.
MTK remained undefeated until October, as DVSC suffered losses early on to Honvéd and MTK. MTK would only lose two games on home soil under József Garami, and won 6 of their last 7 games. The two teams scored an equal amount of goals, 67.
As of 2024, this remains MTK's most recent league-title.
