Marko Vujin (Serbian Cyrillic: Марко Вујин, born 7 December 1984) is a Serbian handball player who plays for German club THW Kiel and for the Serbian national team.
Vujin started his professional career in his hometown club RK Sintelon, where he played with national team mate Žarko Šešum and Bosnian top goalkeeper Danijel Šarić, who later won the EHF Champions League with FC Barcelona Handbol.
In July 2003, he was signed by the Hungarian Championship outfit Dunaferr SE, who were strengthening their squad for the forthcoming EHF Cup campaign.
Vujin spent three years with the Danube-side and collected a championship bronze medal in each season. Although during his spell in Dunaferr the club did not manage to break the dominance of the Pick Szeged–MKB Veszprém duo, he showed his unique scoring skills and was crowned as the top scorer of the Hungarian Championship in the 2005–2006 season.
With his brilliant performances he drew the attention of MKB Veszprém KC, and the record champions secured the services of the right back in the summer of 2006. In his new club Vujin has grown into a player of the highest calibre and became the key of Veszprém's success. He helped the team to the EHF Cup Winners' Cup title in 2008 with scoring nine goals in the first leg of the finals, that was eventually won by the Hungarian club with a five-goal margin.
