曼海蒂（Mehndi或Mehendi，印地语：मेहन्दी；又称Henna，阿拉伯语：الحناء，al-ḥinnā）彩绘纹身是一种以印度指甲花为颜料的人体彩绘艺术，它源于美索不达米亚，已有千多年的历史，至12世纪成为印度文化，盛行于印度、巴基斯坦及中东，尤其在婚嫁时，都会在新娘的手掌及脚上绘上悦目的图案作为装饰。

指甲花是一种棕色的纯植物油性颜料，因为不含化学物质，又不会引起痛楚或导致皮肤敏感，所以成人或小童皆可在身上彩绘。彩绘约可维持一星期，直至因新陈代谢将留在皮肤表层的颜料排出体外。

Mehndi or henna is a paste that is bought in a cone-shaped tube and is made into designs for men and women. Mehndi is derived from the Sanskrit word mendhikā. The use of mehndi and turmeric is described in the earliest Hindu Vedic ritual books. It was originally used for only women's palms and sometimes for men, but as time progressed, it was more common for women to wear it. Haldi (staining oneself with turmeric paste) as well as mehndi are Vedic customs, intended to be a symbolic representation of the outer and the inner sun. Vedic customs are centered on the idea of "awakening the inner light". Traditional Indian designs are representations of the sun on the palm, which, in this context, is intended to represent the hands and feet.
