Reinhard Johannes Sorge was a German dramatist and poet. He is best known for writing the Expressionist play The Beggar (Der Bettler), which won the Kleist Prize in 1912 and almost singlehandedly created modern theatrical stagecraft. After being subsequently received into the Roman Catholic Church, Sorge began an effort to bring the Catholic literary revival into the literature of the Germanosphere. Instead, Sorge was conscripted into the Imperial German Army in World War I in 1915. He was killed in action during the Battle of the Somme in the summer of 1916.
