Jan Veselý (born 24 April 1990) is a Czech professional basketball player for FC Barcelona of the Spanish Liga ACB and the EuroLeague.

Veselý began playing basketball with the youth clubs of Příbor and BK Snakes Ostrava in the Czech Republic.

[7] On 9 April 2012, he recorded his first double-double, finishing the game with 11 points and 11 rebounds in a win over the Charlotte Bobcats.

Eventually, Fenerbahçe finished in 4th place in the EuroLeague, after losing in the third-place game to CSKA Moscow, by a score of 80–86.

[15][16] On 21 March 2016, it was announced that he would be sidelined for up to six weeks, due to an Achilles tendon injury, which caused him to miss the entire EuroLeague playoffs against Real Madrid.

In his return, he'd record 14 points, in an 88–77 overtime victory against them, while also being announced as a part of the All-EuroLeague First Team, for his performances in the 2015–16 Euroleague season, before his Achilles tendon injury.

On 9 July 2016, Veselý signed a new three-year contract with Fenerbahçe, with NBA opt-out clauses every summer.
