Marko Marin (Serbian Cyrillic: Марко Марин, born 13 March 1989) is a German former professional footballer who played as an attacking midfielder and left winger.

After a year at Mönchengladbach's academy, he was promoted to the reserve team; he was offered a three-year contract which he signed and later went on to make his professional début with the club on 31 March 2007 against Eintracht Frankfurt.

On 9 August 2008, Marin scored a hat-trick within the first 16 minutes of Mönchengladbach's 8–1 thrashing of seventh division club VfB Fichte Bielefeld in the first round of the DFB-Pokal.

Following the departure of Özil to Real Madrid in August 2010, however, Marin's form dropped noticeably, as he notched only one goal and five assists during Bremen's 2011–12 Bundesliga campaign.

[12] Marin's only goal of the Bundesliga campaign came on 18 February 2012, when he opened the scoring in the ninth minute of a 3–1 derby victory over Hamburger SV at the Imtech Arena.

[13] In Marin's final game for Bremen, he provided the telling ball for Markus Rosenberg's goal, but this was not enough as his side succumbed to a 4–1 away defeat to VfB Stuttgart on 13 April.

[20] He made his Premier League debut on 28 November, replacing Eden Hazard in the 82nd minute of a 0–0 draw in the West London derby at home to Fulham.

[23] On 28 June 2013, Chelsea confirmed that they had reached an agreement for the season-long loan of Marin to Sevilla, subject to the completion of legal documentation and a medical.

[25] Marin started on the bench in the Europa final, coming on late in the second half, and then substituted in extra-time as Sevilla beat Benfica 4–2 in penalties.

In the sixth minute, Marin was able to pick up Aquilani's pass and clipped home the opening goal, as Fiorentina edges out the French side in a 2–1 win.

[2] On 20 January 2015, after an unsuccessful loan spell at Fiorentina, Marin joined Anderlecht for the remainder of the season, with an option to buy at the end of the campaign.

[31] Five days after moving to Belgium, Marin made his debut coming off the bench, replacing Maxime Colin in the 75th minute in a 2–0 loss to Standard Liège.

[32] Marin was in the starting line-up of the Belgian Cup Final, although he was substituted in the second-half after suffering a hamstring injury as Anderlecht lost 2–1, with Lior Refaelov scoring a late volley.

[33] Anderlecht decided to pass on the option to buy Marin at the end of the season after he suffered a hamstring injury during the Belgium Cup final which ruled him out for several weeks.

It was the sixth consecutive victory for team of experienced manager Takis Lemonis and the Reds climbed at first Super League position, with 32 points after 15 matches, one more than rivals AEK and PAOK.

Almost three weeks later, on 6 November 2018 to be exact, Marin was once again involved in Red Star's first ever Champions League campaign, this time by assisting Milan Pavkov's first goal in their historic 2–0 win against Liverpool.
