Misilyah (Arabic: مسلية), sometimes spelled Mithiliyeh and Misiliyeh, is a Palestinian village in the northern West Bank of the State of Palestine, located 14 kilometers south of the city of Jenin.

[4] The plain, Marj al-Gharaḳ, also spelled Merj el-Ghǔrǔk, which lacks any natural drainage, was described at the beginning of the 20th century as transforming into a large swamp during the rainy season, only to dry up in summer, when the resulting field was cultivated with grain.

[9] In 1838, Edward Robinson noted the village when he travelled in the region, as bordering the extremely fertile Marj Sanur.

[11] In 1870, Victor Guérin noted it, "sitting on the northern slopes of a hill planted with superb olive trees; at the bottom there is a fertile and well-cultivated plain.

"[12] In 1882, the PEF's Survey of Western Palestine described Meselieh: "A small village, with a detached portion to the north, and placed on a slope, with a hill to the south, and surrounded by good olive-groves, with an open valley called Wady el Melek (' the King's Valley') on the north.
