Max Adalbert (born Johannes Adolph Krampf; 19 February 1874 – 7 September 1933) was a German stage and film actor.

Adalbert was born in Danzig (Gdansk), Imperial Germany as Maximilian Adalbert Krampf to a Prussian Officer.

Coming in contact with Curt Bois, Adalbert turned into a comedian and co-founded the popular Kabarett der Komiker in December 1924.

On 30 May 1931 he made his debut as the central character of Carl Zuckmayer's Der Hauptmann von Köpenick at the Deutsches Theater in Berlin, which was filmed in the same year.

Max Adalbert died of pneumonia while in Munich for a guest performance, and was buried at the Stahnsdorf South-Western Cemetery near Berlin.
