The Ezzedeen Al-Qassam Brigades (Arabic: كَتَائِبُ عِزِّ الدِّينِ الْقَسَّامِ), usually shortened to Al-Qassam Brigades, is the military wing of the Palestinian Sunni Islamist political organisation Hamas. They operate in the Gaza Strip and are responsible for various military activities, including rocket attacks against Israel. The group was founded in the late 1980s and is named after Izz ad-Din al-Qassam, a Syrian Muslim preacher and nationalist leader who played a role in the Arab anti-colonial struggle in the early 20th century. The Brigades have been involved in conflicts with Israel.
Al-Qassam spokesperson, Abu Obaida stated in a public speech in 2023 during the Israeli war on Gaza that 85% of their recruits are orphans who wish for revenge whose parents were killed by the Israeli Forces.
The leader of the Al-Qassam Brigades, is Izz al-Din al-Haddad (as of 2025's second quarter).
