The 2005âÂÂ06 Croatian First Football League (officially known as the Prva HNL Oà ¾ujsko for sponsorship reasons) was the fifteenth season of the Croatian First Football League, the national championship for men's association football teams in Croatia, since its establishment in 1992. The season started on 20 July 2005 and ended on 13 May 2006. Hajduk Split were the defending champions, having won their eighteenth championship title the previous season. Dinamo Zagreb won the title, after a win against Osijek on 6 May 2006, which started his eleventh year dominance.

Playoff wasn't needed after the second-placed Croatian Second Football League team, Belià ¡ÃÂe, failed to secure a license to compete in Prva HNL. Therefore, MeÃÂimurje automatically kept their first-league status for the 2006âÂÂ07 season.
