Umm al-Faraj (Arabic: أم الفرج, known to the Crusaders as La Fierge), was a Palestinian village, depopulated in 1948.

The village was situated on a flat spot in the Acre plain, 10.5 kilometers (6.5 mi) northeast of Acre.

Archaeological remains from the Roman and Byzantine eras have been found here.

Sugar Moulds found here indicate that sugar productions started in the 11th century, under the Fatimid era.

The village was known to the Crusaders as Le Fierge, and belonged to the fief of Casal Imbert. In 1253 King Henry granted the whole estate of Casal Imbert, including Le Fierge, to John of Ibelin. Shortly after, in 1256, John of Ibelin leased Az-Zeeb and all its depending villages (including Le Fierge) to the Teutonic Order for 10 years. In 1261, Az-Zeeb, together with Le Fierge and Le Quiebre, were sold to the Teutonic Order, in return for an annual sum for as long as Acre was in Christian hands. In 1283 it was still a part of the Crusader states, as it was mentioned as part of their domain in the hudna between the Crusaders based in Acre and the Mamluk sultan Qalawun.

According to al-Maqrizi, it had come under Mamluk rule in 1291, when it was mentioned under the name of Farah when sultan al-Ashraf Khalil allocated the village's income to a Waqf in Cairo.

Sugar production continued here during the Crusader and Mamluk eras.

Incorporated into the Ottoman Empire in 1517 with all of Palestine, it appeared in the 1596 tax registers as Farja, being in the Akka Nahiya (Subdistrict of Acre), part of the Safad Sanjak (District of Safed), with a population of 24 households and 13 bachelors, all Muslim. The villagers paid a fixed tax rate of 20% on agricultural products, including wheat, barley, summer crops, cotton, goats and beehives, in addition to "occasional revenues" and a water mill; a total of 1,576 akçe. Half of the revenues were given to a waqf. Sugar production continued here to the beginning of the seventeenth century CE.
