List of British flyweight boxing champions is a table showing the boxers who have won the British flyweight title. The title has been sanctioned by the National Sporting Club since 1909, and later by its replacement British Boxing Board of Control (BBBoC) since 1929.
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.
