Young Corbett II (October 4, 1880 – April 10, 1927; born William H. Rothwell) was an American boxer who held the World Featherweight championship.

During this time he also engaged in a number of non-title matches, including one against Young Erne and two against Jimmy Briggs, both of which Corbett won.

[3] Attempts to match British World Featherweight Champion Ben Jordan with Young Corbett were not successful.

Corbett had trouble making the featherweight limit of 126 pounds, and some sources claim he relinquished his title and moved to the lightweight division in December 1902.

He met future world champion Battling Nelson in two consecutive fights in 1904 and 1905, losing both by technical knockout.
