Patrick Kohlmann (born 25 February 1983 in Dortmund, Germany) is a German-Irish football player who plays for Union Berlin.
Born in Dortmund to a German father and Irish mother, Kohlmann began his football career with BV Westfalia Wickede, before moving on to TSC Eintracht Dortmund. In 1993, he impressed big club Borussia Dortmund and signed for their youth team.
Kohlmann was to stay at Borussia Dortmund for 14 years, where he elevated from youth player to playing for the second team. His chances with the first team were limited, often as an unused sub. He finally got his chance in 2004 versus 1. FC Kaiserslautern but went off with a bad knee injury. It was to be his only season as a first team squad member.
In 2007, Kohlmann signed for Regionalliga Nord side Rot-Weiß Erfurt and helped in their push for promotion to 3. Fußball-Liga. The next season he joined fellow 3. Liga side 1. FC Union Berlin.
Kohlmann represented the Republic of Ireland national under-21 football team five times. He made his debut on 19 August 2003, against Poland. He was also in the squad of Irish U-20 in 2000. Kohlmann was eligible to represent Ireland because of his Irish mother.
