PS Sudan is a passenger-carrying side-wheel paddle steamer on the River Nile in Egypt. Along with PS Arabia, she was one of the largest river steamers in Thomas Cook's Nile fleet. Some scenes of the ITV television film of Agatha Christie's Death on the Nile were filmed aboard Sudan.

Death on the Nile is a work of detective fiction by British writer Agatha Christie, published in the UK by the Collins Crime Club on 1 November 1937 and in the US by Dodd, Mead and Company the following year. The UK edition retailed at seven shillings and sixpence (7/6) and the US edition at $2.00.) The book features the Belgian detective Hercule Poirot. The action takes place in Egypt, mostly on the River Nile. The novel is unrelated to Christie's earlier (1933) short story of the same name, which featured Parker Pyne as the detective.
