Boško Janković (Serbian Cyrillic: Бошко Јанковић; born 1 March 1984) is a Serbian former footballer who played as a midfielder for the Serbia national football team. He is an attacking minded player, with the tendency to take long shots and free kicks.
Having gone through all age groups in Red Star Belgrade youth setup, 18-year-old Janković earned his first taste of full squad action throughout fall 2002, during first half of 2002–03 season under head coach Zoran Filipović.
However, over the winter 2002–03 break in January 2003, Janković was loaned out to lower division side Jedinstvo Ub along with Dušan Basta and Aleksandar Luković in order to gain valuable experience through regular playing time. Over the next season and a half in Ub, he excelled in attacking midfielder position, scoring 21 league goals in 28 matches. At the beginning of 2003–04 league season, Jankovic along with a group of other Red Star youth players was registered both for Red Star and Jedinstvo, which in practice meant that he trained with Red Star during the week while playing league matches for Jedinstvo on Saturdays. However, following the winter break, head coach Slavoljub Muslin decided to discontinue this practice making the players both train and play with Jedinstvo.
