Kalpavriksha is a wish-fulfilling divine tree in Hindu mythology. Kalpavriksha is an artistic and literary theme common to the Hindu Bhagavatas, the Jains and the Buddhists. Kalpavriksha is the tree of life, also meaning "World Tree" finds mention in the Vedic scriptures. In the earliest account of the Samudra manthan or "churning of the ocean of milk" Kalpavriksha emerged from the primal waters during the ocean churning process along with Kamadhenu, the divine cow that bestows all needs.

Adansonia digitata L. is the Kalpvriksha.

Ficus benghalensis is not, it is Vatvriksha.

In some places Cocos nucifera L. is also called Kalpvriksha, but it is not so.
