All These Sleepless Nights (Polish: Wszystkie nieprzespane noce) is a 2016 Polish docufictional film by Michał Marczak. Shot over a year and a half, the film focuses on real life friends Krzysztof Baginski and Michal Huszcza as they party around Warsaw and how their relationship struggles when Baginski begins a relationship with Eva Lebeuf, the French-Polish ex-girlfriend of Huszcza.

The film premiered at the 2016 Sundance Film Festival where Marczak won the directing prize in the World Cinema - Documentary category. While the film went on to play various documentary festivals around the world, Marczak was openly indifferent to the idea of categorizing his film as a documentary, giving various interviews in which he talked about how certain scenes in the film were staged.
