The 2015–16 season was Vasas Football Club's 85th competitive season, 114th year in existence as a football club and first season in the Nemzeti Bajnokság I after winning the second division in the previous season. In addition to the domestic league, Vasas participated in that season's editions of the Magyar Kupa.
Besides Vasas, MTK played their home games in the Illovszky Rudolf Stadion due to the Hidegkuti Nándor Stadion in Budapest, built in 1947, being demolished to make way to the newly built Hidegkuti Nándor Stadion. During the season, MTK changed their temporary stadion to Dunaújváros due to the condition of the pitch deteriorating because of the unusual weather conditions and high loads.
On 19 October 2015, Károly Szanyó, who earned promotion, was sacked for the team being in a relegation spot and replaced by Antal Simon. His mandate expired on 31 December 2015, and Simon was replaced by German Michael Oenning on the first day of the new year.
In the last round, they were battling with Puskás Akadémia to avoid relegation, and they eventually came out on top after beating MTK 2–0.
