Ta'ashur (Hebrew: תְּאַשּׁוּר, lit. 'Larch') is a moshav in southern Israel. Located in the north-western Negev between Ofakim and Netivot, it falls under the jurisdiction of Bnei Shimon Regional Council and covers an area of around 1,200 dunams. In 2022 it had a population of 461.

The moshav was established in 1953 by Moroccan Jewish immigrants and refugees. Its name is taken from the Book of Isaiah, specifically Isaiah 41:19:

I will plant in the wilderness the cedar, the acacia-tree, and the myrtle, and the oil-tree; I will set in the desert the cypress, the plane-tree, and the larch together;

Two other nearby moshavim, Brosh (cypress) and Tidhar (plane-tree) take their name from this passage and the three of them are known as the Moshavei Yahdav (lit. the "Together Moshavim").
