On 5 January 2020, Marin signed for the Saudi Arabian club, Al-Ahli a €6 million contract until the summer of 2022, for an estimated transfer fee in the range of €2.5 million.

Before the start of the 2019–20 season, Red Star's general director Zvezdan Terzić confirmed that Marin would become the new club captain.

After Red Star Belgrade qualified for the 2018–19 UEFA Champions League group stage (their first ever appearance in its current format), Marin signed a three-year contract with the club for an estimated transfer fee in the range of €700,000 and was registered in the last hour of the summer transfer window in Serbia.

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. On 13 March 2019, Marin agreed to extend his contract with Red Star to the summer of 2021. Marin was voted MVP in the 2018–19 season and was also therefore included in the team of the season.

On 17 December 2017, thanks to an impressive long-range effort by the German attacking midfielder, Olympiacos won 1–0 against PAS Giannina. 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.

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. 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.

Marin previously played for Bundesliga clubs Borussia Mönchengladbach and Werder Bremen, before signing for Chelsea in 2012. He spent most of his time out on loan at four clubs in four countries before leaving for Olympiacos in 2016, then Red Star Belgrade in 2018.

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. 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. Marin ended his time with the Bremen club after scoring eight goals in 87 Bundesliga appearances.

On 28 April 2012, Marin agreed a deal with English Premier League club Chelsea. He signed a five-year deal with Chelsea, keeping him at the club until 2017. Marko Marin was given the number 21 shirt, previously worn by Salomon Kalou, who left Chelsea for Lille OSC.

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. Marin did show his skill in Bremen's eight goal game against SC Freiburg on 20 August 2011. He provided assists for Claudio Pizarro, Marko Arnautović and Wesley as Bremen secured a 5–3 win.

In 2010, Marin stated that he never received a call from Bosnia and Herzegovina and Serbia, so he decided to play for Germany.

Marin was included in Germany's provisional squad for the 2010 FIFA World Cup in South Africa announced in May 2010, and following a string of impressive performances in warm-up games (most of which he played as a substitute), was named in the final 23-man squad. He would go on to play twice at the World Cup in South Africa, both as a substitute in Germany's 4–0 win over Australia and in the subsequent 1–0 loss to Serbia. After disappointing performances, however, notably in the game against Serbia, Marin was not selected for any more games, as Germany finished third in the tournament.

On 24 June 2009, Marin was sold for €8.2 million from Borussia Mönchengladbach to Werder Bremen. He was a part of Bremen's attack comprising Aaron Hunt and Mesut Özil, which lit up the Weserstadion. In the 2010–11 season, he showed his quality, scoring four league goals and providing 11 assists.

A full German international from 2008 to 2010, he won 16 caps and represented the country at the 2010 World Cup, where they came third.

In 2007, Marin also received a call up to his under-21 national squad and has since played on nine occasions. On 16 May 2008, it was announced that Marin would be included in senior squad coach Joachim Löw's provisional 26-man squad for UEFA Euro 2008. He did not, however, make the final 23. He made his debut on 27 May 2008 in a 2–2 draw against Belarus. Marin entered the game as a half-time substitution for Bastian Schweinsteiger. He was eventually cut from the final squad on 28 May 2008.

In 2005, Marin moved to the Borussia Mönchengladbach youth academy. 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.

Marin was born in Gradiška, SR Bosnia and Herzegovina, SFR Yugoslavia, today Bosnia and Herzegovina, to Bosnian Serb parents, mother Borka Marin and father Ranko Marin. Marin was only two years old when the family moved to Germany in 1991 due to his mother's job. Growing up in Frankfurt, Marin began playing football with local clubs.
