Postern of Fate is a mystery novel by Agatha Christie, first published in the UK by the Collins Crime Club in October 1973 and in the US by Dodd, Mead and Company later in the same year. The UK edition retailed at £2.00 and the US edition at $6.95.

The book features her detectives Tommy and Tuppence Beresford and is the detectives' last appearance. It is the last novel Christie wrote, but not the last to be published as it was followed by two unpublished novels written in the 1940s.

The Beresfords are depicted as a retired couple, but they begin to investigate a cold case dating to the First World War. The case involves the poisoning of a female spy.

This is one of only four Christie novels not to have received an adaptation of any kind—the others being Death Comes as the End, Destination Unknown and Passenger to Frankfurt.
