Natural dyes and their application play an important role in different purposes like in textiles, cosmetics, food products etc. Initially natural dyes were the only option to the people for coloring of different fabrics, but after the discovery of first synthetic dye in1856, it has altered the dependency on natural dye. Synthetic dyes have gently reduced the production cost & certain applications but have raised a question mark on environmental issues and health safety. On the other hand, natural dyes can be derived from natural sources like roots, leaves and bark of trees, secretion of animal, insects, invertebrates, fungi, minerals etc. They are environment friendly, have less side effect and more effective. Natural dyes encounter some inherent difficulties of uniform use and the uniformity of the dye itself. But they have gained the industry's attention since they have greater environmental compatibility and improved biodegradability. So, instead of having some drawbacks, the textile industries have started a huge amount of use of natural dyes on coloring of different fabrics. People have started to utilize the natural dyes for their beneficiary purposes. This study attempts to review on different sources, classification, and various applications of natural dye on textile fabrics
