Yasid (Arabic: ياصيد) is a Palestinian town in the Nablus Governorate in northern West Bank, located 15 kilometers northeast of Nablus. According to the Palestinian Central Bureau of Statistics (PCBS), the town had a population of 2,291 inhabitants in mid-year 2006 and 2,505 by 2017.

Yasid is located 8.6 km north of Nablus. It is bordered by Wadi al Far’a to the east, the village of Siris to the north, Beit Imrin and Jaba’ to the west, and Talluza and ‘Asira ash Shamaliya villages to the south.

Sherds from Iron Age (I-II) Persian early and late Roman, Byzantine, Early Islamic and Medieval periods have been found here.

Yasid was identified with Yaṣat or Yaset (Hebrew: יצת), mentioned in the 9th–8th century BCE Samaria Ostraca (No. 9,-10, 19 and 47) and later in the 6th-7th century Mosaic of Reḥob as a Jewish village in the region of Sebastia which was inhabited mostly by non-Jews and, therefore, agricultural produce obtained from the area could be taken by Jews without the normal restrictions imposed during the Sabbatical years, or the need for tithing.

Yasid, like the rest of Palestine, was incorporated into the Ottoman Empire in 1517, and in the census of 1596 it was a part of the nahiya ("subdistrict") of Jabal Sami which was under the administration of the liwa ("district") of Nablus. The village had a population of 47 households and 2 bachelors, all Muslim. The villagers paid taxes on wheat, barley, summer crops, olive trees, beehives and/or goats, in addition to occasional revenues and a tax on Muslims in the Nablus area; a total of 7,340 akçe.

In 1838, Yasid was located in the Haritheh District, north of Nablus.

In 1882, in the PEF's Survey of Western Palestine (SWP), Yasid was described as "A village of moderate size on a knoll, with a few trees."

In the 1922 census of Palestine conducted by the British Mandate authorities, Yasid had a population of 308 Muslims, increasing in the 1931 census to 372; 369 Muslims and 3 Christians, in 67 houses.
