The Lonely God is a short story, written by Agatha Christie. This romantic story was first published in The Royal Magazine in July 1926. It has later been published in the short story collections While the Light Lasts and Other Stories and The Harlequin Tea Set and Other Stories.

In her autobiography Christie writes that she wrote The Lonely God after reading the novel The City of Beautiful Nonsense, which she found was regrettably sentimental.
