Baharu is a census town and a gram panchayat in the Jaynagar I CD block in the Baruipur subdivision of the South 24 Parganas district in the Indian state of West Bengal.

"Chand Sadagar, a merchant character of the Manasavijaya, reached Baruipur, from Kalighat, through the old Bhagirathi channel.

From there he proceeded towards Chhatrabhog, and then traveling through Hatiagarh pargana reached the open sea".

Rama Chandra Khan, the zamindar of Chhatrabhog, helped Chaitanyadeva to continue with his journey.

In the southern portion of the subdivision (shown in the map alongside) there are 20 census towns.

The entire district is situated in the Ganges Delta and the southern part is covered by the Baruipur-Jaynagar Plain.

Archaeological excavations at Dhosa and Tilpi, on the bank of the Piyali River indicate the existence of human habitation around 2,000 years ago.

After the partition of India, refugees from erstwhile East Pakistan and Bangladesh had a strong impact on the development of urban areas in the periphery of Kolkata.
