The 1998–99 Nemzeti Bajnokság I, also known as NB I for short, was the 97th season of top-tier football in Hungary. The league is officially named Professzionális Nemzeti Bajnokság (PNB) for sponsorship reasons. The season began on 24 July 1998 and ended on the weekend 16 June 1999. Újpest are the defending champions, having won their 20th Hungarian championship at the end of the 1998–99 season.

MTK won their 21st national title, finishing 19 points above Ferencváros, and 20 points above defending champions Újpest. MTK were already leading the table before the winter-break by 11 points. By Gameweek 26 they had extended their lead to 14 points. MTK's championship was confirmed on Gameweek 30, after defeating Gázszer 2-0 at Hungária Körút. Sándor Egervári's men only lost two home games throughout the season, and won 10 consecutive league games between November and April.
