'Ficus religiosa' or sacred fig is a species of fig native to the Indian subcontinent and Indochina that belongs to 'Moraceae', the fig or mulberry family. It is also known as the bodhi tree, peepul tree, peepal tree, the pipal tree, or the Ashvattha tree (in India and Nepal). The sacred fig is considered to have a religious significance in three major religions that originated on the Indian subcontinent, Hinduism, Buddhism, and Jainism.

Hindu and Jain ascetics consider the species to be sacred and often meditate under it. This is the tree under which Gautama Buddha (an acetic and founder of the religion of Buddhism) is believed to have attained enlightenment. The sacred fig is the state tree of the Indian states of Odisha and Haryana.
