Marda (Arabic: مرده) is a Palestinian town in the Salfit Governorate of the State of Palestine, in the northern West Bank, 18 kilometers southwest of Nablus. A previously important rural and religious center under the Mamluks and Ottomans, it had a population of 2,375 in 2017.

Marda is 3.6 kilometers (2.2 mi) north of Salfit. It is bordered by Iskaka and Jamma'in villages to the east, Salfit to the south, Kifl Haris and Qira villages to the west, and Jamma'in village to the north. The Israeli settlement of Ariel lies immediately south of Marda.

According to Ellenblum, no remains from the Byzantine era have been found here. According to Ben-Zvi, there was a Samaritan population in Marda during the Fatimid period. The village is mentioned as Marda and Mardan in the 14th century Samaritan Chronicle.

During the Crusader period, Diya' al-Din (1173–1245) writes that there was a Muslim population in the village, and that followers of Ibn Qudamah lived here. The maternal grandmother of Diya' al-Din came from Marda.

Yakut (1179–1229) noted that Marda was a "village near Nablus". Ben-Zvi cites a Samaritan text according which a priest by the name of Isaac son of Abraham who had resided in Marda relocated to Gaza, presumably during Saladin's rule, and it appears that the Samaritan community there lasted up until this time.

Marda flourished in the 12th-16th centuries as a center for Islamic jurisprudence and Hanbali learning. Muslim biographical dictionaries list 55 scholars from Marda, including important Hanbali chief judge, Amin-ed-dyn 'Abd-er-Rahman, was born in the village in the early 15th century.

Marda was incorporated into the Ottoman Empire in 1517 with all of Palestine, and in 1596 it appeared in the tax registers under the name of Marda, as being in the nahiya ("subdistrict") of Jabal Qubal, part of the Sanjak of Nablus. With a population of 163 Muslim households, it was the largest rural center in the entire district, second only to Tulkarm. During this era it was an important market town, one of the largest in the area. The residents paid a fixed tax-rate of 33.3% on agricultural products, including wheat, barley, summer crops, olive trees, goats and beehives, in addition to occasional revenues, a press for olive oil or grape syrup, and a market toll; a total of 25,634 akçe. All of the revenue went to a Muslim charitable endowment.

In the 18th and 19th centuries, Marda formed part of the highland region known as Jūrat Marda or Bilād Jammā‘īn. Situated between Dayr Ghassāna in the south and the present Route 5 in the north, and between Majdal Yābā in the west and Jammā‘īn, Mardā and Kifl Ḥāris in the east, this area served, according to historian Roy Marom, "as a buffer zone between the political-economic-social units of the Jerusalem and the Nablus regions. On the political level, it suffered from instability due to the migration of the Bedouin tribes and the constant competition among local clans for the right to collect taxes on behalf of the Ottoman authorities."
