The Gaza envelope (Hebrew: עוטף עזה, otef aza) encompasses the populated areas in the Southern District of Israel that are within 7 kilometres (4.3 mi) of the Gaza Strip border and are therefore within range of mortar shells and Qassam rockets launched from the Gaza Strip. The area is defined by the Anemone coronaria flowering during spring which is celebrated in the Darom Adom festival. Most of the population in the area resides in kibbutzim.

The border between Israel and the Gaza Strip was established in the 1949 Armistice Agreement between Israel and Egypt, signed at the end of the 1948 Arab–Israeli War, and was further defined in the agreement of February 1950. Many communities on the Israeli side of the border (such as Sa'ad and Nirim) were established even before that, while others (such as Sderot and Nahal Oz) were founded not long after the demarcation of the border. However, the term "Gaza envelope" has been applied to these communities only in the 21st century.

Following Israel's unilateral disengagement from the Gaza Strip in 2005, there was an increase in cross-border shelling and rocket attacks into Israel. Data collected by the Israeli Security Agency showed an increase in shelling from 401 shells in 2005 rising year-on-year to 2,048 in 2008 before falling back to 569 in 2009. In response to the increase in shelling, in 2007 the Knesset passed the "Assistance to Sderot and the Western Negev (Temporary Provision) Law, 2007", which recognized these communities (and additional communities in the area designated by the Minister of Finance's order) as "Confrontation-line Communities" and gave them special privileges (temporarily, until the end of 2008). Additional legislative measures extended the validity of some of the benefits, with certain changes, until the end of 2014. This area came to be known colloquially as the "Gaza envelope."

In June 2014, it was reported that the Home Front Command decided to cut the budget of the Coordinators of Comprehensive Security ("Ravshatzim") in communities in the Gaza envelope. Leaders of the authorities in the Gaza envelope turned to the Minister of Defense, Moshe Ya'alon, in a letter to cancel this decision. Shortly thereafter, the 2014 Gaza War began, during which the communities in the Gaza envelope were subjected to rocket and mortar attacks. In addition, combat tunnels were exposed, penetrating from the Gaza Strip into Israel, and there were several incidents where militants entered through the tunnels and attacked IDF soldiers. As a result of the fighting, many residents evacuated their homes.

In the 2014 Gaza War, impacts to residents in the Gaza envelope was greater than that of other Israeli citizens, due to their exposure to short-range rocket fire, extensive mortar shelling, and several casualties. Another threat to the residents of the Gaza periphery was the underground tunnels from the Gaza Strip into Israel. Many such tunnels were destroyed in the 2014 Gaza War, and the excavation and destruction continued in the years that followed.

After several years of calm following the 2014 Gaza War, during which plans were made for the emergency evacuation of communities in the Gaza envelope, on March 30, 2018, clashes began at the Gaza–Israel barrier – a series of mass protests in the Gaza Strip.

As part of the protests, Palestinian activists and militants clashed with the Israel Defense Forces near the system fence around the Gaza Strip. Thousands of Palestinians approached the fence, with some throwing stones and Molotov cocktail and explosive devices. The events continued since then,^[when?] including the launching of incendiary kites from the Gaza Strip into Israel with the aim of igniting areas beyond the fence. As a result hundreds of fires occurred in the Gaza envelope, burning hundreds of hectares of fields and forests, as well as agricultural facilities.

In August 2018, hundreds of rockets and mortar shells were fired towards communities in the Gaza envelope.
