Tantura (Arabic: الطنطورة, al-Tantura, lit. The Peak; Hebrew and Phoenician: דור, Dor) was a Palestinian Arab fishing village located 8 kilometers (5 mi) northwest of Zikhron Ya'akov on the Mediterranean coast of Mandatory Palestine. Near the village lie the ruins of the ancient Phoenician city of Dor.

The village stood on a low limestone hill overlooking the shoreline of two small bays. The water was supplied from a well in the eastern part of the village. The al-Bab gate was in the southeast of the village. The Roman ruins were on the coast to the north with the hill of Umm Rashid to the south. In 1945 it had a population of 1,490.

The village was targeted in the early stages of the 1948 Arab–Israeli War, with its houses looted and its Arab Palestinian inhabitants expelled and others massacred by the Palmach underground Alexandroni Brigade. The Tantura massacre was first documented by a Palestinian politician in 1951, decades before a 2022 Israeli documentary revealed testimony from several IDF veterans affirming that a massacre, involving somewhere between several to 200 Palestinian victims, had taken place.

Dor was the most southern settlement of the Phoenicians on the coast of Syria and a center for the manufacture of Tyrian purple, extracted from the murex snail found there in abundance. Dor is first mentioned in the Egyptian Story of Wenamun, as a port ruled by the Tjeker prince Beder, where Wenamun (a priest of Amun at Karnak) stopped on his way to Byblos and was robbed.

According to the Book of Joshua, Dor was an ancient royal city of the Canaanites commanding the heights, whose king became an ally of Jabin of Hazor in the conflict with Joshua (Jos 11:1-2; Jos 12:23). Dor is also mentioned in the Book of Judges as a Canaanite city whose inhabitants were put to 'taskwork' when the area was allotted to the tribe of Manasseh (Judges 1:27–28). In the Book of Kings, Dor was said to be incorporated into David's Israelite kingdom. In the 10th century BCE, it became the capital of the Heights of Dor under Solomon, and was governed by his son-in-law, Ben-abinadab as one of Solomon's commissariat districts (1 Kings 4:11).

Josephus Flavius in his Antiquities of the Jews (14:333) describes Dor as an unsatisfactory port where goods had to be transported by lighters from ships at sea. Dora was the city where Antiochus, ruler of the Hellenistic Seleucid Empire with the aid of Simon Maccabaeus, laid siege to the usurper Trypho. During Pompey's invasion of Judea, Dora was razed, along with all the coastal towns, only to be rebuilt under Gabinius's direction.

Dor was an important salt production site, as attested to by pools and channels dug along the coast.

By the mid-3rd century CE, the city had deteriorated to little more than a fishing village.
