Ross Alexander Collins (April 25, 1880 – July 14, 1968) was a U.S. Representative from Mississippi.

He was admitted to the bar in 1901 and commenced practice in Meridian, Mississippi.

Collins was elected as a Democrat to the Sixty-seventh and to the six succeeding Congresses (March 4, 1921 – January 3, 1935).

In 1929, Collins successfully proposed the Library of Congress's $1.5 million purchase of Otto Vollbehr's collection of incunabula, including one of four remaining perfect vellum copies of the Gutenberg Bible.

In the late 1930s he was the chairman of the House Subcommittee on District Appropriations; during his time in office, he cut spending on local DC funds for welfare and education stating that "my constituents wouldn't stand for spending money on niggers".
