Sean "Masher" Dodd (born 28 June 1984) is a British professional boxer. He held the Commonwealth lightweight title from 2017 to 2018 and challenged twice for the British lightweight title in 2015 and 2016.
Dodd made his professional debut on 3 March 2012, scoring a fourth-round technical knockout (TKO) over Giuseppe Daparto at the Northgate Arena in Chester.
After winning his first eight fights, two by stoppage, he fought Andy Townend for the vacant Central Area super-featherweight title on 10 May 2014 at the Doncaster Dome in Doncaster. Dodd suffered the first defeat of his career via seventh-round TKO.
He bounced back from defeat with two points decision (PTS) victories against Liam Richards in March and Gary Buckland in September, before challenging Scott Cardle for the British lightweight title on 7 November 2015 at the Echo Arena in Liverpool. Dodd suffered the second defeat of his career via TKO in the twelfth and final round. At the time of the stoppage, he was ahead on two of the judges' scorecards at 107–103 and 105–104, while the third judge had it 105–104 in favour of Cardle. The pair would meet again in a rematch five months later on 2 April 2016, again at the Echo Arena. In what some described as a controversial decision, Cardle retained his title through a majority draw (MD), with two judges scoring the bout even at 114–114 while the third scored it 116–112 in favour of Cardle.
