13 Demon Street is a Swedish horror television series that aired between 1959 and 1960 in American syndication. Thirteen 25-minute episodes were produced.

Lon Chaney Jr. was the host, introducing each episode from his 'home' at 13 Demon Street. Condemned for some shockingly atrocious crime, Chaney's purpose in relating the series' stories was to convince viewers that the crimes presented in them were worse than his, thus freeing him from his purgatory. This was hard for audiences to judge, however, because Chaney's original crime was never specified.

Three episodes of the series were edited together to make a theatrical feature called The Devil's Messenger, in which Chaney's character was reconfigured as Satan himself. Chaney filmed new wraparound segments to link the chosen episodes, which were 'The Photograph', 'The Girl in the Glacier' and 'Condemned in Crystal'.
