The Newgate Calendar, subtitled The Malefactors' Bloody Register, was a popular publication whose first edition came out in 1774.

The "Calendar", in five volumes, comprised the biographies of celebrated criminals and their crimes since the year 1700. A new edition was published in 1824 by Andrew Knapp and William Baldwin, two lawyers, and a further edition in 1826, under the title, The New Newgate Calendar. The title refers to London's notorious Newgate prison.
