Enter the Saint is a collection of three interconnected adventure novellas by Leslie Charteris first published in the United Kingdom by Hodder and Stoughton in October 1930, followed by an American edition by The Crime Club in April 1931.

The stories in Enter the Saint mark the first series appearance of Scotland Yard Inspector Claud Eustace Teal, a character that Charteris had introduced in the 1929 novel, Daredevil.

The introductions of Roger Conway and Dicky Tremayne, the two operatives featured prominently in this volume, are perfunctory and it is left to the reader to assume that they have a longstanding relationship with the Saint.

For the next 30 years Charteris would alternate between novel, novella, and short story formats; this would continue after other authors began writing the Saint series in the 1960s.

The three novellas were published in the magazine Thriller prior to being collected: "The Lawless Lady" was adapted as an episode of The Saint starring Roger Moore and first broadcast on 30 January 1964.
