Celtis timorensis, commonly known as stinkwood or stinking wood, is a species of flowering plant in the family Cannabaceae that grows in tropical Asia.

[4] The most notable characteristic of the tree is the strong excrement odour that it emits from the bark and sap, which pervades the surrounding forest.

[5] In Sri Lanka the heartwood of the tree (known as gurenda, ගුරෙන්ද) is used as a traditional ayurvedic medicine against syphilis, chickenpox, and measles.

The tree is found throughout the tropical regions of Asia, from India and Sri Lanka, through Indo-China, southern China and Malesia to the Philippines.

It occurs on Christmas Island, an Australian territory in the northeastern Indian Ocean, where it forms about 1% of the primary rainforest canopy.
