The 2023–24 season was Unión Deportiva Almería's 35th season in existence and second consecutive season in La Liga, the top flight of association football in Spain. They also competed in the Copa del Rey.
On 3 February 2024, Almeria lost 2–1 to Valencia, thus reaching 23 matches from the start of the season without a win, putting them in dubious company alongside the infamous 1997–98 Sporting Gijón team, the only other side in La Liga history to fail to win any of their opening 23 matches. Almería then overtook Sporting Gijón's record following a 0–0 draw at home to Athletic Bilbao in their following match.[1] On 18 February, Almería drew 1–1 away at Granada, breaking Levante's previous record of 28 consecutive matches without a win in La Liga.[2] On 27 April, the club was formally relegated to the second division following a 1–3 home defeat against Getafe.
