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 has been sanctioned by the National Sporting Club since 1909, and later by its replacement British Boxing Board of Control since 1929.

r–Champion relinquished title.
s–Champion stripped of title.
