The Israeli disengagement from Gaza (Hebrew: תוכנית ההתנתקות, Tokhnit HaHitnatkut) was the unilateral dismantling in 2005 of the 21 Israeli settlements in the Gaza Strip and the evacuation of Israeli settlers and army from inside the Gaza Strip.

The disengagement was proposed in 2003 by Prime Minister Ariel Sharon, adopted by the government in June 2004, and approved by the Knesset in February 2005 as the Disengagement Plan Implementation Law. It was implemented in August 2005 and completed in September 2005. The settlers who refused to accept government compensation packages and voluntarily vacate their homes prior to the 15 August 2005 deadline were evicted by Israeli security forces over a period of several days. The eviction of all residents, demolition of the residential buildings and evacuation of associated security personnel from the Gaza Strip was completed by 12 September 2005. The eviction and dismantlement of the four settlements in the northern West Bank was completed ten days later. 8,000 Jewish settlers from the 21 settlements in the Gaza Strip were relocated. The settlers received an average of more than US$200,000 in compensation per family.

The United Nations, international human rights organizations and many legal scholars regard the Gaza Strip to still be under military occupation by Israel. This is disputed by Israel and other legal scholars. Following the withdrawal, Israel has continued to maintain direct control over Gaza's air and maritime space, and six of Gaza's seven land crossings, it maintains a no-go buffer zone within the territory, and controls the Palestinian population registry, and Gaza remains dependent on Israel for its water, electricity, telecommunications, and other utilities.
