Alvin Morell Bentley III was an American politician from the U.S. state of Michigan. As four-term a U.S. representative from 1953 to 1961, he made national headlines as one of the wounded of the 1954 United States Capitol shooting.

The 1954 United States Capitol shooting was an attack on March 1, 1954, by four Puerto Rican nationalists seeking to promote Puerto Rican independence from the United States. They fired 30 rounds from semi-automatic pistols onto the legislative floor from the Ladies' Gallery of the House of Representatives chamber within the United States Capitol.
