The 2021–22 TSV Havelse season was the 110th season in the football club's history and first in the 3. Liga, the third flight of German football. TSV Havelse will also participate in this season's edition of the Lower Saxony Cup. This is the first season for Havelse in the HDI-Arena, located in Hanover, Lower Saxony, Germany, since their home stadium, the Wilhelm-Langrehr-Stadion in Garbsen, did not meet 3. Liga standards.
