Mahli is the name of a tribe of India. It is a scheduled tribe of the state of West Bengal and Jharkhand (earlier these areas were part of Bihar). They mostly reside in Santhal Parganas and certain other regions of Jharkhand, and in the adjoining areas of West Bengal. Their population is dwindling. Mahli people traditionally earned their livelihood by selling articles made of bamboo. Some typical articles made by them are: Machi (a small bench), umbrellas, soop (used in kitchen, to remove dust from cereals), sop and chatai (for lying down and sleeping), raincap (special cap covering head, and upper back for protection from rains during work).
Mahli people typically have a tattoo of their name on their hand.
