A blockade has been imposed on the movement of goods and people in and out of the Gaza Strip since Hamas's takeover in 2007, led by Israel and supported by Egypt. The blockade's current stated aim is to prevent the smuggling of weapons into Gaza; previously stated motivations have included exerting economic pressure on Hamas. Human rights groups have called the blockade illegal and a form of collective punishment, as it restricts the flow of essential goods, contributes to economic hardship, and limits Gazans' freedom of movement. The blockade and its effects have led to the territory being called an "open-air prison".

A blockade is the act of actively preventing a country or region from receiving or sending out food, supplies, weapons, or communications, and sometimes people, by military force. A blockade differs from an embargo or sanction, which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than a fortress or city and the objective may not always be to conquer the area.
