Israel Exploration Society (IES) is a non-profit organization whose goal is to further historical, geographical and archaeological research concerning the Land of Israel. Over the years, it has organized and sponsored some of the most important archaeological projects carried out in the country. It plays a key role in archaeological research covering all periods from prehistoric times to the Ottoman period, coordinating much of the multi-institutional archaeological research conducted by Israeli and foreign archaeological expeditions.

Major activities include organizing excavations, enlisting financial support for archaeological projects, and cooperation with Israeli and foreign institutions in the field of publication in a collective effort to promote the cause of archaeology.

The IES disseminates knowledge gained from the exploration of Israel to the general public in Israel and abroad, through annual archaeological conferences, meetings, and congresses. It publishes excavation reports and other archaeological volumes, including the bi-annual Israel Exploration Journal and the bi-annual Hebrew-language journal Qadmoniot.
