The kibbutz was founded on 2 November 1945, the anniversary of the Balfour Declaration, by young Palmach members.
It was located on the northern part of the depopulated Palestinian village of Hunin.

New immigrants from Europe, the United States and South America began to settle there in the late 1970s.

On 7 April 1980, five terrorists from the Iraqi-backed Arab Liberation Front penetrated Misgav Am in the night and entered the nursery.
They killed the kibbutz secretary and an infant boy and held the rest of the children hostage, demanding the release of about 50 terrorists held in Israeli prisons.
The first raid of an IDF infantry unit was unsuccessful, but a second attempt, a few hours later, succeeded, and all the terrorists were killed.
Two kibbutz members and one soldier were killed, four children and 11 soldiers were wounded.

Immediately after the attack, Israeli troops entered southern Lebanon to wipe out terrorist nests and to intensify the pressure on the Palestinian terrorists in Lebanon.
Israel withdrew after five days, because of heavy political pressure by the United States.
In the years of Israeli presence in southern Lebanon (1982–2000), the kibbutz had cordial relations with the people on the other side of the border, despite the state of war between Lebanon and Israel since 1948.

During the Second Lebanon war in 2006, several thousands of IDF troops were deployed around Misgav Am, which brought heavy logistical problems regarding food, water and sanitary facilities.
