Johannes Theodor Baargeld, pseudonym of Alfred Emanuel Ferdinand Grünwald (9 October 1892 - 9 October 1927), was a German painter and poet who, together with Max Ernst, founded the Cologne Dada group.

He was born in Stettin, Germany, which is now Szczecin, Poland.

Baargeld was the editor of the periodical Der Ventilator ("The Fan"), which was started by Max Ernest and Hans Arp in 1919, and he collaborated on many other Dadaist publications such as Bulletin D, Dada W/3 and others.

He gave up painting in 1921 and died in an avalanche while climbing Aiguille de Bionnassay in the French Alps.
