2015–16 Nemzeti Bajnokság III

The 2015–16 Nemzeti Bajnokság III was Hungary's third-level football competition. The group winner and runner-up teams in each of the three groups were promoted, while the best third placed team overall were also promoted.

The championship was won by Ferencváros II, Kozármisleny, and Nyíregyháza. However, Ferencváros II could not be promoted to Nemzeti Bajnokság II since reserve teams could not get promotion to Nemzeti Bajnokság III.
