Mallaha (Arabic: ملاّحة) was a Palestinian Arab village, located 16 kilometers (9.9 mi) northeast of Safed, on the highway between the latter and Tiberias. 'Ain Mallaha is the local Arabic name for a spring that served as the water source for the village inhabitants throughout the ages. It is also one of the names used in English to refer to the ancient Natufian era settlement at the site.

Evidence of settlement at Mallaha (or 'Ain Mallaha) dates back to the Mesolithic period circa 10,000 BCE. The first permanent village settlement of pre-agricultural times in Palestine, Kathleen Kenyon describes the material remains found there as Natufian, consisting of 50 circular, semi-subterranean, one-room huts, paved with flat slabs and surrounded by stone walls up to 1.2 meters (3.9 ft) high. The floors and walls of the homes were decorated in solid white or red, a simple and popular decorative motif in the Near East at the time. The inhabitants appear to have subsisted on fish from nearby Lake Hula, as well as by hunting and gathering; no evidence of animal domestication or cultivation has been found, with the exception of dogs: the burial of a human being with a domestic dog at the site represents the earliest known archaeological evidence of dog domestication.

During the Crusader era, the Franks referred to Mallaha as Merla. Ibn al-Qalanisi describes a battle that took place at Mallaha in June 1157 between the Arab and Turkish forces of Nur ad-Din Zangi and those of the Crusaders under King Baldwin III. Qalanisi writes that Nur ad-Din sent his troops to Mallaha immediately after learning via pigeon post that the Franks had set up an encampment there. The battle, as described by Qalanisi, was bloody and quick, resulting in decisive victory for the Muslim forces, who are reported to have lost only two men, with the king narrowly escaping with a bodyguard. The battles for control over Mallaha continued. The Itinerary of Richard I notes that the army had advanced to Merla, "where the king had spent one of the previous nights."

Just SE of Mallaha (at grid 2071/2737), excavations have revealed structures, probably dating to thirteenth or fourteenth century, that is after the area fell to Mamluk sultan Baybars. The structures have been assumed to belong to a sugar-producing installation.

Mallaha, like most of Palestine, was incorporated into the Ottoman Empire in the early sixteenth century. Sufi traveller al-Bakri al-Siddiqi passed by the village in the mid-eighteenth century.^{[dubious – discuss]}

Johann Ludwig Burckhardt travelled in the region during the start of the nineteenth century, but according to Edward Robinson, who travelled there in 1838, Burckhardt mislabeled the whole S.W. coast of the lake as el-Mellahah. Robinson observed that Ain el-Mallaha lay northwest of Lake Hula, and was "a single large fountain." Nearby was "usually a large encampment of the Ghawarineh in tents and reed huts."

In 1881, the PEF's Survey of Western Palestine (SWP) described Ain el Mellahah as a "very large perennial spring, flowing in a long stream from the base of the mountain; at once turns a mill, and forms almost a small river."

During the British Mandate, Mallaha had a roughly rectangular configuration that stretched from north to south, and its residents predominately sustained themselves through agriculture. In the 1922 census of Palestine, Mallaha had a population of 440 residents, all Muslim. By the 1931 census, the population increased to 654 residents across 161 households.
