Tell el-Hesi (Hebrew: תל חסי‎) is a 25-acre archaeological site in Israel. It was the first major site excavated in Palestine, first by Flinders Petrie in 1890 and later by Frederick Jones Bliss in 1891 and 1892, both sponsored by the Palestine Exploration Fund (PEF). Petrie's excavations were one of the first to systematically use stratigraphy and seriation to produce a chronology of the site.
