John Peter Toohey (September 18, 1879 - November 7, 1946, New York City) was an American writer and publicist.
He was a reporter for the Scranton Tribune and around 1900 joined the Washington Post and the New York Evening World before moving into publicity.
He co-wrote two comedic plays produced on Broadway, Swifty (1922) with Walter C. Percival, and Jonesey (1929) with Anne Morrison.
From 1930 to 1942, Toohey was "general representative," i.e., the chief publicist, of the Broadway producer Sam H. Harris's company.
Toohey was portrayed by actor Jake Johannsen in the film Mrs. Parker and the Vicious Circle (1994).
