Tur Shimon (Hebrew: טור שמעון) or Horvat Tura, the Hebraized form of Khirbet et-Tantura ("Ruin of the Point"), so-called after the shape of the hill, is an archaeological site in Nahal Sorek, Israel.

The hilltop ruin is covered with brushwood and wild growth, ashlars, a partially standing wall of field stones, razed structures, and large rock-cut cisterns.

On the northeastern slope of the ruin is a tunnel measuring c. 80 meters long, ending in a rock-hewn pit with niches resembling a columbarium (dovecote).

On the southwest slope of the mountain are seen other traces of the town's material culture: a columbarium carved into the rock, a lime pit for burning limestone, a cistern and a wine press.

The fertility of the region is highlighted in rabbinic lore, which states that the inhabitants of Tur Shimon prepared 300 sealed jars of summer produce every week.

Conder, describing the terrain in July 1881, wrote: "Riding down the great gorge which, under various names, runs down from near Gibeon to Beth Shemesh, we gradually ascended the southern slopes in the vicinity of the little ruined village of Deir esh Sheikh.

Conder and Kitchener who visited the valley in the late 19th century under the auspices of the Palestine Exploration Fund noted that a branch of an ancient Roman road passed alongside the mountain on its southern side, leading from Bethlehem to Beth-shemesh.

Boaz Zissu, who conducted an archaeological survey of the site in 1992–1997 for the Israel Antiquities Authority, dated the town to the 2nd century BCE and believes it is named for Simon the Hasmonaean, who was known as a builder of fortresses.
