The Agatha Christie Memorial is a memorial to author and playwright Agatha Christie, located at the intersection of Cranbourn Street and Great Newport Street by St Martin's Cross near Covent Garden, in London, United Kingdom.

This was chosen to pay homage to Christie's contribution to theatre: her 1952 murder mystery play The Mousetrap is the world's longest-running show, and she was the first female playwright to have three plays performing simultaneously in the West End.

[2][4] The idea to create this memorial was conceived and implemented by Christie's grandson Mathew Prichard together with Sir Stephen Waley-Cohen, producer of The Mousetrap since 1994.

[2] Westminster City Council gave formal consent and offered advice on its construction.

On the memorial appear some titles of her most popular books and plays, in English, and in some of the many languages into which Christie's work has been translated.
