J. T. McIntosh (born February 14, 1925 in Paisley, Renfrewshire, Scotland) is a pseudonym used by Scottish writer and journalist James Murdoch MacGregor.
MacGregor used the McIntosh pseudonym (along with its variants J. T. MacIntosh, and J. T. M'Intosh) as well as "H. J. Murdoch", for all his science fiction work, which was the majority of his output, though he did publish books under his own name. His first story, "The Curfew Tolls", appeared in Astounding Science Fiction during 1950, and his first novel, World Out of Mind, was published during 1953.
