"In a Good Cause—" is a science fiction short story by Isaac Asimov. The story first appeared in a 1951 edition of the anthology New Tales of Space and Time and was reprinted in the collection Nightfall and Other Stories (1969).

The story commences in the year 2755 of the "Atomic Era" (corresponding to 4700 CE in Asimovean chronology) and opens with a description of a statue on the grounds of the United Worlds organisation raised to Richard "Dick" Altmayer. It displays a quote and three dates, which correspond to the three days upon which he was arrested for his beliefs.
