The ancient city of Halasa or Chellous (), Elusa (ΕΛΟΥϹΑ) in the Byzantine period, was a city in the Negev near present-day Kibbutz Mash'abei Sadeh that was once part of the Nabataean Incense Route. It lay on the route from Petra to Gaza. Today it is known as Haluza (), and during periods of Arab habitation it was known asal-Khalūṣ (; Early Muslim period) and Al-Khalasa (20th century).
