"Kill Now—Pay Later" is a Nero Wolfe mystery novella by Rex Stout, first serialized in three issues of The Saturday Evening Post (December 9, 16 and 23–30, 1961).

It first appeared in book form in the short-story collection Trio for Blunt Instruments, published by the Viking Press in 1964.

Wolfe's aging Greek bootblack is accused of murder and Wolfe feels he owes him something since he (apparently) listens eagerly to Wolfe's dissertations on ancient Greek culture during every shoe-shining session and moreover has told the police that "Wolfe is a great man".
