Abdelkader Hachani (/ɑːbdɪlˈkɑːdər ˈhɑːʃəni/ ⓘ; Arabic: عبد القادر حشاني; 26 December 1956 – 22 November 1999) was a leading figure and founding member of the Islamic Salvation Front (or FIS), an Algerian Islamist party.

Following the arrests of Abassi Madani and Ali Belhadj on 30 June 1991, he became the party's effective leader (after four days of contested leadership by Mohamed Said.)

He led the party to victory in the National Assembly elections of December 1991; shortly afterwards, he was arrested on 22 January 1992.

He played a prominent role in negotiating the Islamic Salvation Army's (AIS) cease-fire of October 1997, but condemned President Abdelaziz Bouteflika's Civil Harmony Act.

Hachani was shot by an assassin in the waiting room of a dental clinic in the Bab El Oued district of Algiers on 22 November 1999, and he subsequently died in hospital.
