"The Terrible Old Man" is a short story of fewer than 1200 words by American writer H. P. Lovecraft.

It is notable as the first story to make use of Lovecraft's imaginary New England setting, introducing the fictional town of Kingsport. The story, about the fate of three would-be robbers of the titular old man's house, has been criticized by Peter Cannon for being an openly xenophobic polemic against immigration.
