Tel Arad (Hebrew: תל ערד) or Tell 'Arad (Arabic: تل عراد, romanized: Tall ʿArād) is an archaeological site consisting of a lower section and a tell or mound. It is located west of the Dead Sea, about 10 kilometres (6 miles) west of the Israeli city of Arad in an area surrounded by mountain ridges which is known as the Arad Plain. The site is about 10.1 ha (25 acres) in size.

The site comprises two parts: a Canaanite settlement on lower ground and a Judahite fortress and settlement on a hill. The Canaanite settlement was inhabited from the early 4th to the mid 3rd millennium BCE, while the Judahite habitation was established in the 10th century BCE and continued until 135 CE during the Bar Kokhba revolt. After a period of abandonment, the settlement was reinhabited in the 7th century CE during the Early Muslim period and was used for approximately two centuries.

The lower and upper sites are part of the Tel Arad National Park, which has undertaken projects to restore the upper and lower sites and opened them to the public. Tel Arad has been excavated in the 20th and 21st centuries.

It was first identified in modern literature in 1841 by Edward Robinson in his Biblical Researches in Palestine, on account of the similarity of the Arabic place name, Tell 'Arad, with the Arad in the Book of Joshua.

Yoel Elitzur observes that although the site remained uninhabited for the last 1,100 years, the name has endured, preserved by nomads.

The lack of Middle and Late Bronze Age remains seems to invalidate the identification with biblical, i.e. Canaanite Arad. On the other hand, the two Hebrew ostraca containing the name Arad confirm the site as being the Iron Age, i.e. Israelite Arad. One theory trying to solve the problem suggests that "the Negev of Arad" was only the name of the surrounding region at the time, with no city in existence. A second theory places Canaanite Arad at Tel Malhata [fr], 8 mi (13 km) southwest of Tel Arad, where archaeologists found substantial Middle Bronze Age fortifications. An argument in favour of the latter theory is Pharaoh Sheshonk's list of captured cities, with one "Arad the House of YRHM", possibly at Tel Arad and referring to the settling there of Jerahmeelite families, and another "Great Arad" (possibly Tel Malhata) towering over the "Negev of Arad".

Tel Arad is positioned on the northern edge of the southern Israeli Beersheba–Arad Valley, defined by scholars as "the eastern (biblical) Negev", the Hebrew Bible using the term Negev only for the northern part of the region known today by that name.

This east-west oriented valley was a convenient route for caravans during periods of sustained commercial activity.
