Titas River (Bengali: তিতাস Titash) is a trans-boundary river of eastern Bangladesh. It originates in the state of Tripura in India where it is known as Haora River in Bengali and Saidra in the local Kokborok language. Flowing near Agartala, (India), it enters Bangladesh through Akhaura Upazila in the Brahmanbaria District of Bangladesh, then merges with the Meghna River to the south near Ashuganj Upazila. The length of the river is about 98 km. There is another river of the same name which starts as a distributary of the Meghna and flows back into it.
Many legends about Titas and Meghna traverse from generation to generation in world's largest deltaic country Bangladesh. One such legend says that Titas is the daughter of Meghna, who has been carrying her progeny to the Bay of Bengal since time immemorial. Amazingly enough, the two streams never commingle, and they keep a conspicuous demarcation line between them. While many hydrographers attribute this phenomenon to the difference in water properties of the two rivers, the people cherish to think of them as mother-daughter.
