The Lion In Love is a 1960 play by the British dramatist Shelagh Delaney.

[5] The Lion in Love had an Off-Broadway professional run in the United States in 1963.

[8] Response to the play was largely negative, both critically and commercially, but in retrospect it has been seen as a success by ordinary standards.

Darlington disapproved of its kitchen sink milieu, Bernard Levin, one of the new breed of critics, wrote, "The fact is, Miss Delaney is not only a shrewd and penetrating observer; she is a very delicate artist.

[12] In 1979 she adapted her BBC series The House That Jack Built for Off-Off-Broadway's Cubicolo Theatre.
