Martin Beck (1867 – November 16, 1940) was a vaudeville theatre owner. He owned Orpheum Circuit, Inc.

Beck immigrated to the United States from Liptovský Mikuláš, Austria, (today Slovakia) in 1883 with a troupe of actors. He worked as a waiter in a Chicago beer garden, then went to San Francisco with the Schiller Vaudeville Company in the early 1890s. Beck became friends with the owner of the Orpheum Theatre in San Francisco, and when it was bought by Morris Meyerfeld in 1899, he helped Morris expand by acquiring other theaters. By 1905, Beck was running the organization, which extended from Chicago to San Francisco.

In the spring of 1899, twenty-five-year-old Harry Houdini met Beck at a beer hall in St. Paul, Minnesota where Houdini was performing. Beck telegraphed Houdini from Chicago: "You can open Omaha March twenty sixth sixty dollars, will see act probably make you proposition for all next season." Houdini wrote at the bottom of telegram, "This wire changed my whole Life's journey."

He built the Palace Theatre in 1913. Sarah Bernhardt's performance here may be credited with the early success of this theatre.

He was voted out of the presidency of Orpheum Circuit, Inc. after it went public in 1923. Martin then opened the Martin Beck Theater in 1924.

Orpheum Circuit, Inc. merged with the chain started by Benjamin Franklin Keith and Edward Franklin Albee II on January 28, 1928 to form the Keith-Albee-Orpheum Corporation. A few months later, Joseph P. Kennedy and David Sarnoff of RCA merged KAO with Film Booking Office of America (FBO) to form the Radio-Keith-Orpheum (RKO) movie studio.

He returned to vaudeville in 1932, running the booking office at RKO, and in 1934 brought the D'Oyly Carte Opera Company to America for the first time.

He died at Mount Sinai Hospital in Manhattan on November 16, 1940.
