Super featherweight, also known as junior lightweight, is a weight division in professional boxing, contested between 126 pounds (57 kg) and up to 130 pounds (59 kg).

The first English champion was "Battling Kid" Nelson in 1914 who lost his title to Benny Berger in 1915. Artie O’Leary also won this title in 1917. This weight class appeared into two distinct historical periods, from 1921 to 1933 and 1960 to the present.
