"The Truth" is a fantasy novel by British writer Terry Pratchett, the twenty-fifth book in his Discworld series.

The book features the coming of movable type to Ankh-Morpork, and the founding of the Discworld's first newspaper by William de Worde, as he invents investigative journalism with the help of his reporter Sacharissa Cripslock. The two investigate the charges of embezzlement and attempted murder against Havelock Vetinari, and help vindicate him.

The Ankh-Morpork City Watch characters also appear in this novel, but have limited roles and are seen mainly from de Worde's perspective. C.M.O.T. Dibbler also puts in an appearance.
