Peter Schuyler Miller (February 21, 1912 – October 13, 1974) was an American science fiction writer and critic.

Miller was raised in New York's Mohawk Valley, which led to a lifelong interest in the Iroquois Indians.

He subsequently worked as a technical writer for General Electric in the 1940s, and for the Fisher Scientific Company in Pittsburgh from 1952 until his death.

After his death his sister Mary E. Drake donated his extensive collection of papers, maps, books and periodicals, accumulated largely as a result of his review work, to the Carnegie Museum.

They now form the basis of the P. Schuyler Miller Memorial Library at the Edward O'Neill Research Center in Pittsburgh.
