Rantiya (Arabic: رنتيّة, known to the Romans as Rantia and to the Crusaders as Rentie) was a Palestinian village, located 16 km (9.9 mi) east of Jaffa. During the British Mandate in Palestine, in 1945 it had a population of 590 inhabitants.

Those inhabitants became refugees after a 10 July 1948 assault by Israeli forces from the Palmach's Eighth Armored Brigade and the Third Infantry Battalion of the Alexandroni Brigade during the 1948 Arab-Israeli war.

Of the over 100 houses that made up the village, only three remain standing today. The Jewish localities of Mazor, Nofekh, and Rinatia are located on Rantiya's former lands.

Ranṭyā /Ranṭya/ is an ancient name which perfectly matches the Greek Ῥαντία. The name is apparently related to that of Ranṭīs which is a Grecized form of a Hebrew name (Rmtym, LXX Aρμαθαιμ); with t > ṭ under the influence of r.

During the Crusader era the village was known as Rentie, Rantia, or Rentia.

The village was situated on a low mound on an ancient site.

In 1122 the tithes of the village were granted to the hospital of the church of St John at Nablus. In 1166, the tithes were granted to the Knights Hospitaller. A vaulted building in the village, named al-Baubariya, has been dated to the Crusader period.

Rantiya, like the rest of Palestine, was incorporated into the Ottoman Empire in 1517, and in 1557 the revenues of the village were designated for the new waqf of Hasseki Sultan Imaret in Jerusalem, established by Hasseki Hurrem Sultan (Roxelana), wife of Suleiman the Magnificent. Administratively, the village belonged to the Sub-district of Ramla in the District of Gaza. In the late 1550s, local disturbances decreased the income from the village by nearly 40%.
