Salbit (Arabic: سلبيت, also spelled Selbît) was a Palestinian Arab village located 12 kilometers (7.5 mi) southeast of al-Ramla. Salbit was depopulated during the 1948 Arab–Israeli War after a military assault by Israeli forces. The Israeli locality of Shaalvim was established on the former village's lands in 1951.

In 1883 the PEF's Survey of Western Palestine identified Salbit with Shaalabbin (Biblical Hebrew: Šʽlbyn/*Šʽlbyt), which was located 5 kilometers (3.1 mi) northwest of biblical Aijalon (modern day Yalo).

Jerome (347–420) describes it as part of the territory of the Dan, transcribing its name at that time as Selebi, a form also used by Josephus (37-c. 100).

In 1949, archaeologists excavated the remains of a Samaritan synagogue there that was dated to the late 4th or early 5th century. Measuring 15.4 × 8 metres, its mosaic floor contains one Greek inscriptions and two in Samaritan (language and script). In the centre of the mosaic is a mountain which is thought to be a depiction of Mount Gerizim, the holiest site in Samaritanism. Rectangular in shape, the synagogue was longitudinally aligned more or less towards Mount Gerizim.

Salbit was not mentioned in 16th century records. It was an 'azba of Biddu and nearby villages (including Beit Duqqu and Beit 'Anan).

In 1838, it was noted as Selbit, a Muslim village in the Ibn Humar area in the District of Er-Ramleh.

In 1883 the PEF's Survey of Western Palestine (SWP) described Selbit: "Foundations and caves. The ruins are extensive. A square building stands in the middle. There is a ruined reservoir lined with cement, and walls of rubble."

The village is believed to have been resettled in the late 19th century. By the beginning of the 20th century, it was inhabited by residents from Biddu settled the site, establishing it as a dependency – or satellite village – of their home village.
