List of British lightweight boxing champions

List of British lightweight boxing champions is a table showing the boxers who have won the British lightweight title. The title had been sanctioned by the National Sporting Club from 1909–1929 where they awarded the Lord Lonsdale Challenge Belt until its later replacement by the British Boxing Board of Control (BBBoC) since.

A champion may retire or voluntarily relinquish the title in order to fight for a higher-ranked championship. Where the date on which a champion relinquished the title is unclear, the date of the last BBBoC sanctioned fight is shown.

r–Champion relinquished title.

s–Champion stripped of title.
