HaAh HaGadol 6 (Hebrew: האח הגדול 6; lit. The Big Brother 6) is the sixth season of the Israeli version of the reality show Big Brother. The season began broadcasting on 14 May 2014 and ended on 30 August 2014. Fifteen housemates entered the house during the premiere. For the first time in Israel, four housemates from previous seasons and one ex-housemate who left the house for medical reasons came back as official housemates and competed again for the main prize.

This season also created controversy, because of the Israel-Gaza conflict, which forced the housemates, when they heard the sirens of the rockets, to go to a safe area of the house.
