Mark Delaney is an English boxer^[1] who fought professionally between 1993 and 2000. He is the younger brother of former Commonwealth Cruiserweight Champion Garry "The Hammer" Delaney.

He was born in Bromley-by-Bow on 1 December 1971 and boxed as a schoolboy and amateur before his first professional fight against Lee Sara in October 1993. He rose steadily through the British rankings until in April 1996 he eventually earned a British Super middleweight title fight against Joe Calzaghe.^[2] The referee stopped the fight in Round 5 with the Welshman comfortably on top, but Calzaghe has acknowledged that the fight, fought in front of a ferociously partisan crowd in Brentwood, Essex, near to Delaney's native East End, hardened him as a professional. Delaney fought on for another four years,^[3] and at one stage was in line for another shot at the British title against Henry Wharton, but the fight never materialized.^[4] His final fight was a British Light Heavyweight Title challenge against Neil Simpson, in which Delaney was caught cold and stopped in the first round. He was hit with a decent headshot by Simpson and went down from a couple of shots to the body. He rose but still looked shaky and the referee stepped in shortly afterwards with Delaney taking punishment on the ropes.
