List of British cruiserweight boxing champions is a table showing the boxers who have won the British cruiserweight title, which has been the British Boxing Board of Control (BBBoC) since 1985.
A champion will often voluntarily relinquish the title in order to fight for a higher-ranked championship, such as the world or European. Where the date on which a champion relinquished the title is unclear, the date of the last BBBoC sanctioned fight is shown.
<sup>r</sup> – Champion relinquished title.<br/> <sup>s</sup> – Champion stripped of title.
