There Shall Be No Night is a three-act play written by American playwright Robert E. Sherwood.

[2] The title comes from a passage in the Book of Revelation (22:5) which is quoted by Lunt's character in Act 3, Scene 6: There shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light...[3]: 150 The play is set in Finland between 1938 and 1940 and concerns a Nobel Prize-winning Finnish scientist (portrayed by Alfred Lunt, whose own stepfather was a Finnish-born physician) and his American-born wife (portrayed by Lynn Fontanne), both of whom are reluctant to believe that the Russians will invade their beloved Finland.

John Mason Brown wrote “No one can complain about the theatre's being an escapist institution when it conducts a class in current events at once as touching, intelligent and compassionate as There Shall Be No Night.”[4] According to William L. Shirer, Sherwood was inspired to write the play by William Lindsay White's moving Christmas broadcast from the Finnish front during the Winter War and his columns for the New York Post.

[6] Sherwood bases his American journalist (portrayed by Richard Whorf) in this play upon W. L. White, substantiating this in his preface to the first published edition by Charles Scribner's Sons in 1940.

[7] Katharine Cornell produced and starred in a television version of the play in 1957 on The Hallmark Hall of Fame with Charles Boyer, Bradford Dillman and Ray Walston.
