Anthony O'Shea (born 9 May 1961 from Stockport, Cheshire) is an English professional darts player who competes in British Darts Organisation events. He was born in Stockport and is of Irish descent. His squat figure has resulted in the nickname Silverback. He has reached the finals of seven BDO major darts tournaments, but to date has never won one. He also acts as a regular commentator for televised BDO coverage.


O'Shea managed to achieve a televised nine dart finish against Adrian Lewis during the 2007 International Darts League on 9 May 2007 which made the tournament the first in darts history to witness two perfect legs. The occasion was made even sweeter as he was celebrating his 46th birthday. O'Shea won the 2008 Welsh Masters, only his second tournament victory. In the 2009 BDO World Championship, O'Shea defeated Anderson in the quarter finals, his best friend Darryl Fitton in the semi final, but was once again second-best in a major final as he lost to Hankey 7–6 in what Tony Green described as the best final since 1992. O'Shea entered the 2009 Winmau World Masters as the number one seed but despite 3–0 wins overs Dave Prins and 8th seed Joey ten Berge, he lost in the semi-finals to defending champion Martin Adams who successfully retained his title. O'Shea then won the WDF World Cup men's singles title with victory over ten Berge in the final, in what was arguably his most significant win to date.


O'Shea won all three group games in the 2010 Grand Slam of Darts, defeating Vincent van der Voort 5–1, James Wade 5–1 and Justin Pipe 5–4. He then lost 10–7 to Terry Jenkins in the second round. In contrast in 2010 where he was world number one, O'Shea came into the 2011 BDO World Darts Championship as the number eight seed and suffered a shock first round loss to Ross Smith.


Tony O'Shea reached his third World Championship final in 2013 after a high quality run. He struggled badly in the final, losing to Scott Waites 7–1 with an average of 81.90. O'Shea became the first man to lose his first three BDO World Championship finals, and only the second player to lose his first three world finals in either the BDO or PDC after Peter Manley.
