2015–16 Nemzeti Bajnokság I/B (men's handball)

The 2015–16 Nemzeti Bajnokság I/B season in men's handball was the second tier of handball competition in Hungary. It sat below the Nemzeti Bajnokság I (NB I) and above the Nemzeti Bajnokság II (NB II). The league consisted of multiple groups, with teams competing within their respective group to qualify for promotion playoffs or avoid relegation to the NB II. The specific number of groups and the number of teams within each group varied from year to year, and are usually determined by the Hungarian Handball Federation. The primary goal for teams was either to win their group and achieve promotion to the NB I, or to secure a high enough position to avoid relegation. The season ran from autumn 2015 to spring 2016. Information regarding specific teams, final standings, and promotion/relegation results for that particular season can be found on the Hungarian Handball Federation's official website or on handball statistics websites.
