Bird Box Barcelona is a 2023 post-apocalyptic horror film directed and written by Álex and David Pastor.

A spin-off sequel to the 2018 film Bird Box, adapted from Josh Malerman's 2014 novel of the same name, the film stars Mario Casas, Naila Schuberth, Georgina Campbell and Diego Calva, and follows Sebastián and his daughter as they begin their own great adventure of survival in Barcelona after an entity of mysterious origin annihilates the world's population causing those who observe it to take their lives.

Everyone is left without blindfolds; Sebastián slowly leads each to open their eyes, and upon witnessing the entities they commit suicide.

They found refuge in a church and met Padre Esteban, a pastor who opined that the entities are angels, and that humanity should be liberated from suffering by embracing death.

Others in the group include Octavio, a Mexican deliveryman with expertise in physics; Roberto and Isabel, a couple; Claire, an English psychiatrist; and Sofia, a young German girl separated from her mother.

Claire undergoes blood tests by scientists who are trying to develop an antibody that can provide immunity against the entities' influence.
