Brcko in Zagreb (Brcko u Zagrebu) is a 1917 Croatian short comedy film directed by Arsen Maas.

The film, created by a band of Zagreb-based theatrical actors and produced by Croatia Film k.d., features a simple plot in which Brcko, the titular protagonist, comes from a province to the big city. It premiered on 28 August 1917 in Zagreb, making it the first Croatian fictional film.

Like all other Croatian fictional films of the era, Brcko in Zagreb is now considered lost. The identity of Arsen Maas remained unknown until 2014, when it was discovered to be an alias of Ante Masovčić, previously known for his theater-related work, and for being a subject of a well-known painting by Miroslav Kraljević.
