The 2002–03 Premier League of Bosnia and Herzegovina was the third season since its establishment and distinguishes itself from previous seasons by having expanded the country-wide league to include the clubs from Republika Srpska in the competition. This season began on 3 August 2002 and ended on 24 May 2003.
The league was won by FK Leotar after a dramatic last round where they defeated away team Rudar Ugljevik (2–1). Široki Brijeg defended successfully against the defending home champions Željezničar (1–0).
