List of British light heavyweight boxing champions

List of British light-heavyweight boxing champions is a table showing the boxers who have won the British light-heavyweight championship. The title has been sanctioned by the National Sporting Club since 1891, and later by its replacement British Boxing Board of Control since 1929.

A champion may retire or voluntarily relinquish the title in order to fight for a higher-ranked championship. Where a champion relinquished the title, the date of his final defence is shown with "(rel)" after it. If he did not defend his title, then "(rel)" is shown after the date at which he won the title.
