In Hindu tradition, Triveni Sangam is the confluence (Sanskrit: sangama) of three rivers that is also a sacred place, with a bath here said to flush away all of one's sins and free one from the cycle of rebirth.
Triveni Sangam is the confluence of the Ganges (Ganga), the Yamuna, and the mythical Saraswati River. Triveni Sangam is located at Prayag – the area of Allahabad neighbouring the confluence; for this reason, the confluence is also sometimes referred to as Prayag.
At Triveni Sangam, the Ganges and the Yamuna can be identified by their different colours – the water of the Ganges is clear while that of the Yamuna is greenish in colour. The third river, the mythical Saraswati, is called invisible.
The auspiciousness of the confluence of two rivers is referred to in the Rigveda, which says, "Those who bathe at the place where the two rivers, white and dark, flow together, rise up to heaven."

In the town of Tribeni in Hooghly district in West Bengal, the river Bhagirathi Hooghly, one of the two main distributaries of the Ganges splits into three more distributaries which are called Ganga, Jamuna and Saraswati. This place is called Tribeni and is of great religious significance to Hindus. It is believed that the "Yukta Veni" (connected) of Prayag in Prayagraj becomes "Mukta Veni" (disentangled) in Tribeni Sangam. At present, due to the changing course of the river in this extremely geologically active Bengal delta region, the Jamuna river of Bengal has almost disappeared and the stream of Saraswati is also rather thin, but in the past all three channels used to carry significant portions of the flow.
