"The Next Witness" is a Nero Wolfe mystery novella by Rex Stout, first published as "The Last Witness" in the May 1955 issue of The American Magazine. It first appeared in book form in the short-story collection Three Witnesses, published by the Viking Press in 1956.

Nero Wolfe is a television series adapted from Rex Stout's series of detective stories that aired for two seasons (2001–2002) on A&E. Set in New York City sometime in the 1940s–1950s, the stylized period drama stars Maury Chaykin as Nero Wolfe and Timothy Hutton as Archie Goodwin. A distinguishing feature of the series is its use of a repertory cast to play non-recurring roles. Nero Wolfe was one of the Top 10 Basic Cable Dramas for 2002.
