Monte Attell, (July 28, 1885-November 11, 1960), born in San Francisco, California, United States, was a champion boxer.

A poor Jewish kid of diminutive stature who was raised in a tough Irish neighborhood, Monte Attell began his career in fighting almost from the first day he could walk outdoors. From fighting for survival in the streets, he turned professional in 1903, winning his first five bouts. He then lost several fights but between February of 1906 and May of 1909, he fought ten times without losing. His performance earned him a chance to fight for the vacant Bantamweight championship.

On June 19, 1909, Monte Attell won the World Bantamweight title when he defeated Frankie Neil at Coffroth's Arena, in Colma, California. Because his older brother Abe Attell (1884-1970) was the then Featherweight Champion of the World, it made them the first brothers to simultaneously hold world boxing titles.

In the seven months following his winning the title, Attell fought seven more times until losing the championship to Frankie Conley on February 22, 1910.

Monte Attell retired from boxing in 1916 because of an eye problem that eventually led to his going blind. On his passing in 1960, he was interred in Cypress Lawn Memorial Park in Colma, California.
