Mamre (; ), full Hebrew name "Elonei Mamre" ("Oaks/Terebinths of Mamre"), refers to an ancient religious site originally focused on a single holy tree, growing "since time immemorial" at Hebron in Canaan. It is known from the biblical story of Abraham and the three visitors . The tree under which he had pitched his tent is known as the oak or terebinth of Mamre. Modern scholars have identified three sites near Hebron which, in different historical periods, have been successively known as Mamre: Khirbet Nimra (a little excavated Persian and Hellenistic period site), Ramat el-Khalil (the best known site), and Khirbet es-Sibte. The last one contained an old oak tree identified by a relatively new tradition as the Oak of Mamre, which has collapsed in 2019, and is on the grounds of a Russian Orthodox monastery.
