Harry "Pittsburgh Phil" Strauss (July 28, 1909 – June 12, 1941) was an American contract killer for Murder, Inc. in the 1930s.

He reportedly killed over one hundred men (some historians put the number as high as 500)[1] using a variety of methods, including shooting, stabbing with ice picks, drowning, live burial, and strangulation.

He was arrested 18 times but was never convicted until he was found guilty of the homicide that sent him and fellow Murder, Inc. hitman Martin "Buggsy" Goldstein to the electric chair.

Like many other Jewish immigrants, the Strauss family settled on the Lower East Side, Manhattan, New York City.

In his youth Strauss started committing crimes and became deeper involved in the streets as the years passed.
