A dybbuk is an evil spirit in Jewish mythology. It is said to be the soul of a dead person, who has transgressed in some way, which returns to inhabit the body of a living person.

The Dybbuk is the title of a play written by S. Ansky in 1914 in Russian or Yiddish, an English version of which was performed in New York in 1925/26.

The play was also made into a 1937 film Yiddish language film with the same title.
