Martin Harnik (born 10 June 1987) is a professional footballer who plays for German fifth-tier club TuS Dassendorf.

At the start of the 2007–08 season, the forward was promoted to the Bundesliga side of Werder Bremen, signing a contract until 2010.

On 15 August 2007, the 20-year-old made his debut for the professional team against Dinamo Zagreb, in the first leg of the third Champions League Qualification round (2–1).

On 24 August 2009, it was announced that Harnik was able to leave his club SV Werder Bremen as a free agent,[5] and six days later was loaned out to Fortuna Düsseldorf.

[7] Harnik began playing for Stuttgart as a joker, but manager Bruno Labbadia brought him into the regular starting squad as the club was fighting relegation in the 2010–11 Bundesliga season.

Media reported he signed a contract until 2021 and estimated the transfer fee paid to Hannover 96 at around €2 million.

[20] Harnik moved down to fifth-division TuS Dassendorf on 7 October 2020, German transfer deadline day.

Harnik, who also was eligible for Germany, opted to play for Austria, although he has never lived there, after having been nominated for the youth national teams of the ÖFB, not those of the German Football Association.
