Houssine Kharja (Arabic: حسين خرجة; born 9 November 1982) is a Moroccan former professional footballer who played as an attacking midfielder.

In the Serie A he played for a number of clubs, including A.S. Roma, Internazionale and Fiorentina, making a total of 117 appearances and scoring 13 goals.

He played four impressive Serie B seasons for the Rossoverdi, gaining a place in the Moroccan national team, and being loaned to Roma in 2005, with the option to buy him in a co-ownership deal for €3.6 million.

At the end of the 2005–06 season, Roma decided not to extend Kharja's loan, so the Moroccan player had to return to Ternana, but he refused to go back and play because in the meantime the Rossoverdi had been relegated to Serie C1.

[5] After appeals, FIGC's court decided that Kharja was a free agent, and so, on 20 March 2007 he signed a three-year contract with Serie B team Piacenza.

In June 2009, Genoa announced the club was reaching an agreement to sign the player[7] and on 2 July the transfer from Siena was completed.
