Tel Rehov (Hebrew: תל רחוב) or Tell es-Sarem (Arabic: تل الصارم), is an archaeological site in the Bet She'an Valley, a segment of the Jordan Valley, Israel, approximately 5 kilometres (3 mi) south of Beit She'an and 3 kilometres (2 mi) west of the Jordan River. It was occupied in the Bronze Age and Iron Age.

The site is one of several suggested as Rehov (also Rehob), meaning "broad", "wide place".

The oldest apiary discovered anywhere by archaeologists, including man-made beehives and remains of the bees themselves, dating between the mid-10th century BCE and the early 9th century BCE, came to light on the tell. In the nearby ruins of the mainly Byzantine-period successor of Iron Age Rehov, a Jewish town named Rohob or Roōb, within it a synagogue with the Mosaic of Rehob, considered one of the most important discoveries from the Roman - Byzantine period and the longest mosaic inscription found so far in the Land of Israel.

Tel Rehov does not correspond to the Hebrew Bible places named as Rehov, of which two were in the more westerly allotment of the Tribe of Asher, and one more northerly.

Identification of Tell es-Sarem/Tel Rehov with the ancient Canaanite and Israelite city of Rehov was based on the preservation of the name at the nearby Islamic holy tomb of esh-Sheikh er-Rihab (one kilometre; 1000 yards to the south of Tel Rehov), and the existence of the ruins of a Byzantine-period Jewish town that preserved the old name in the form of Rohob or Roōb/Roob (one kilometre; 1000 yards northwest of Tel Rehov).

Rehov was one of the largest cities in the region during the Late Bronze Age (1550–1200 BCE) and Iron Age I–IIA (1200–900 BCE). During the Late Bronze Age, while Egypt ruled over Canaan, Rehov was mentioned in at least three sources dated between the 15th–13th century BCE, and again in the list of conquests of Pharaoh Shoshenq I, whose campaign took place around 925 BCE.

Excavations revealed an eight meter wide mud brick fortification wall (with glacis) around the upper mound which the excavators attributed to the Early Bronze III period though no city of that period was found.

The site was clearly occupied during the Late Bronze I and Late Bronze II periods, from 15th century BC to 13th century BC. Actual occupation from this period was found only on a small area (Area D) of the lower mound with possible exposure in probes on the upper mound. Some Egyptian material, including a scarab with the inscription "Scribe of (the) house of (the) overseer of sealed items, Amenemhat" indicates the town may have been under Egyptian control like other towns in the region, after the time of Thutmose III.
