Here is a comprehensive summary of the 2023–24 FC Barcelona season:

  • The 2023–24 season marked Barcelona's 124th year in existence, but they played all home matches at the Estadi Olímpic Lluís Companys due to the ongoing Espai Barça stadium renovation, and it was a transitional year without club legends Sergio Busquets, Jordi Alba, and the retired Gerard Piqué.
  • In the UEFA Champions League, the team topped Group H and advanced to the knockout stage for the first time in three years, defeating Napoli 4–2 on aggregate before their run ended in the quarter-finals against Paris Saint-Germain, largely due to a controversial Ronald Araújo red card in the second leg.
  • Domestically, Barcelona failed to defend their La Liga title, finishing as runners-up, and suffered early exits in the Copa del Rey (quarter-finals to eventual winners Athletic Bilbao) and the Supercopa de España (runners-up).
  • It was Xavi Hernández's final season as head coach, with Hansi Flick confirmed as his successor, while the team scored 110 goals across all competitions, led by Robert Lewandowski with 26.
  • Key summer signings included İlkay Gündoğan, Iñigo Martínez, and Oriol Romeu, while the pre-season featured a US tour that included a 3–0 El Clásico victory over Real Madrid and a 4–2 win against Tottenham to retain the Joan Gamper Trophy.
