骆驼刺属（英语：Alhagi）是生长在旧大陆的其中一个属，常常被叫做camelthorns或manna trees。有三到五个种。

跟其他种类的植物，骆驼刺属的植物有相较长而深的根部。如一株矮树丛长出来只有一公尺高，但是根部可能比十五公尺还长。骆驼刺属的植物很耐干燥，因为长而深的根部可以获取比其他植物位于地底更深层的地下水。

骆驼刺属的植物是鳞翅目蝴蝶幼虫的主要食物。

Alhagi is a genus of Old World plants in the family Fabaceae. They are commonly called camelthorns or manna trees. There are three to five species.

Alhagi species have proportionally the deepest root system of any plants - a 1 m high shrub may have a main root more than 15 m long; due to their deep root system Alhagi species are drought-avoiding plants that utilize ground water, adapting in that way perfectly to the hyper-arid environment.
