John Martin

He signed for Shamrock Rovers in July 2007 and made his debut in a 2–0 victory against Waterford United. Persistent hip and groin injuries saw his performances curtailed for the remainder of the 2007 although he did play a starring role in a 2–0 win against local rivals Bohemians which saw Rovers climb to 2nd in the table. Rovers challenge eventually faded away after a successful return to the Premier League of Ireland under Pat Scully. Numerous injury concerns in 2008 resulted in serious hip surgery in May 2008. Despite being ruled out for the remainder of the season he managed to return for the final 8 games of the season. He claimed his first goal for Rovers against St Patrick's Athletic courtesy of a big deflection from Damian Lynch. A recurrence of the injury in training in November 2008 resulted in additional hip surgery in January 2009 and his retirement on medical grounds.

He signed for Longford Town for the 2004 season. He scored on his 2nd appearance for Longford Town against Shamrock Rovers, scoring with a 25-yard volley moments after coming on to equalise for 10-man Town in a 1–1 draw. The following month he scored 2 goals for Longford in a 4–0 win against local rivals Athlone Town in a league cup tie in St Mels Park. After suffering from a severe bout of tonsillitis he spent numerous weeks out of the team but did return for a league cup semi final win against Finn Harps that Longford won 2–1 thanks to goals from Sean Francis and Dessie Baker. He won his first trophy for Longford after a 2–1 league cup final win against Bohemians in Flancare Park. He scored the first goal in the 2–1 FAI Cup semi final victory against Drogheda United in October 2004 with the winner coming from Seán Dillon in the last minute of extra time. He won his 2nd trophy for Longford in 2004 after another 2–1 victory against Waterford United in the FAI Cup final at Lansdowne Road. He scored twice to relegate Dublin City from the Premier League in the final weeks of the 2004 season. He only missed 3 games in the 2005 season, all through suspension, as Longford failed to hit the heights of 2004 but he did manage to hit winning goals against Waterford and former club UCD as Longford finished the season strongly. A fractured ankle suffered away to Waterford United disrupted most of the 2006 season although he did return from injury to score another goal against Waterford United in the FAI Cup. The loss of several of the FAI cup winning squad saw Town struggle in the 2007 as did a 6-point deduction for licensing issues and Martin left the club in the summer transfer window to sign for Shamrock Rovers in exchange for Jamie Duffy and Ian Ryan. He was previously sent off against Shamrock Rovers when Longford played them earlier in the 2007 season.

His brother Robbie played for Dundalk and Drogheda United. He played with his brother Robert for UCD between 1999–2003 and in Longford Town between 2006–2007. His father Paul played for Rovers in the early 1970s and was part of the famous Athlone Town team that drew with AC Milan in St Mel's Park 1975.

He signed for University College Dublin from Crumlin United in June 1997. He scored on his debut for UCD against Bohemians in August 1997, scoring with a header as college came from 2 goals down in a League Cup tie at Belfield. He scored his 2nd goal in an FAI Cup tie against Home Farm Everton in January 1998 in a 1–1 draw. After a successful debut season he did not feature in the 1998–99 season due to a loss of form and injury. 1999–2000 season saw Martin return to the team as College finished in 4th place in the league to secure a spot in the Inter-Toto Cup. College lost to Bulgarian side FC Velbazhd on away goals after a 3–3 draw in Belfield and a 0–0 away from home. Upon returning from the Inter-Toto cup he helped college secure the FAI Super Cup after a penalty shoot out victory against Bohemians. He scored the opening goal of the 2001 season for College away to Dundalk. He captained UCD in the 2003 season in the absence of regular club captain Tony McDonnell. He departed UCD at the end of the 2003 season after the club's relegation to the first division despite the team losing only 2 of their final 11 games.
