Nadia Hilou (Arabic: ناديا حلو, Hebrew: נאדיה חילו‎; 5 July 1953 – 27 February 2015) was an Arab-Israeli social worker and politician, who served as a member of the Knesset for the Labor Party between 2006 and 2009.

However, in the run-up to the 2006 elections Hilou won 15th place (a slot reserved for women) on Labour's list in the party's primaries.

The party won 19 seats and Hilou took her place in the Knesset, relinquishing her previous positions.

One of her first acts was to co-sponsor a successful bill strengthening laws against cyber sex with minors.

In 2013, her autobiography, titled The Pioneer from Ajami, was published in Hebrew by HaKibbutz HaMeuhad Press.
