An Inspector Calls is a popular drama of 1946, by the British dramatist J.B. Priestley. The play is often studied as part of the school syllabus, and is still frequently performed.

The plot centres on the visit made by a mysterious police inspector to a wealthy and apparently respectable family, for the purposes of enquiring into the death of a poor and unknown girl. The inspector reminds each family member in turn of his or her connection with the girl, leading each of them to suppose that their unintentional cruelty or thoughtlessness has brought about the girl's death.

The 1954 British film version of the play starred Alastair Sim as the Inspector.
