Allar or 'Allar el-Fawqa, also known as 'Allar el Busl, was a Palestinian Arab village located southwest of the Old City of Jerusalem near Wadi Surar, along Wadi Tannur. The name was shared by the twin village of Allar al-Sifla or Khirbat al-Tannur, with official imperial ledgers often listing them both under the single entry of Allar.

Khirbat al-Tannur, also known as Allar al-Sifla, was a Palestinian Arab hamlet in the Jerusalem Subdistrict, near Allar. It was depopulated during the 1948 Arab–Israeli War on October 21, 1948, under Operation Ha-Har. It was located 18.5 km west of Jerusalem.
