This is a list of lineal boxing world champions. An official list of lineal champions in professional boxing is maintained by the Cyber Boxing Zone (CBZ) website, with input from boxing historian Tracy Callis of the International Boxing Research Organization. These were first published in 1994, and are retrospective to the introduction of the Queensberry Rules in 1885. The Transnational Boxing Rankings Board, which promotes the concept of one world champion per weight class, hands out the most complete version of the lineal championship and is recognized by CBZ for maintaining the list of genuine lineal world champions.
