Original Fanwear voetbal tank top FC Barcelona 2019/20

The 2019–20 Futbol Club Barcelona season was the club's 120th season in existence and the 89th consecutive season in the top flight of Spanish football. Barcelona competed in La Liga, Copa del Rey, Supercopa de España and UEFA Champions League. The season covered the period from 1 July 2019 to 14 August 2020.

This club endured its worst season in years, going trophyless for the first time since 2007–08. Head coach Ernesto Valverde was replaced by Quique Setién mid-season after a Supercopa defeat to Atlético Madrid, but that did not improve the team's fortunes, as Barça lost the closely fought title race to Real Madrid and was eliminated by Bayern Munich in the one-legged Champions League quarter-final, infamously losing 2–8.
