Marin Tomasov (born 31 August 1987) is a Croatian professional footballer who plays as a winger or an attacking midfielder for Kazakhstan Premier League club Astana.
Some years after, Tomasov was brought up through the NK Zadar youth academy and in 2006 he signed a professional contract with the senior team and was assigned the number 14 jersey.
His 2008–09 Prva HNL season was especially impressive and Croatian giants Hajduk Split were quick to snap him up in a deal worth over 350,000 euros in the summer of 2009.
He managed only two goals in all of the 2009–10 Prva HNL and even though he was only 20 years old at the time, he stated himself that he was disappointed with his season and will be looking to improve in the future.
Tomasov started the 2011–12 Prva HNL season in exhilarating fashion scoring the winner in the opening game against HNK Šibenik in the 87th minute.
In July 2012, Tomasov joined German 2nd Bundesliga side TSV 1860 München on a three-year contract.
On 5 August 2016, Rijeka and Al-Nassr agreed terms for Tomasov's transfer to the Saudi club, with the deal valued at €2.8 million.
