Blå ("Blue") is a jazz club in Grünerløkka, Oslo, Norway.
It is located at Brenneriveien 9C. Darwin Porter of Frommer's describes the club, ""This is the leading jazz club in Oslo. Dark and industrial, with lots of wrought iron and mellow lighting, this place books some of the best jazz acts in the world. The crowd is a mix of young and old, dressed in casual, but sophisticated attire."[1] Despite this, the club has a run-down appearance with extensive graffiti on the walls of the exterior.
