Jorasanko is a neighbourhood of North Kolkata, in Kolkata district, West Bengal, India. It is so called because of the two (jora) wooden or bamboo bridges (sanko) that spanned a small stream at this point.

Apart from the distinguished seat of the Tagore family, traditionally known as the Jorasanko Thakur Bari, it was also home of the Singhas (including Kaliprasanna Singha), the Pals (including Krishnadas Pal), and the families of Dewan Banarasi Ghosh, Gokul Chandra Daw, Narsingha Chandra Daw, Prafulla Chandra Gain, Tarak Nath Pramanik and Chandramohan Chatterji. "The area thus became the cradle of Bengal Renaissance." It was earlier known as Mechuabazar.

The earliest list of thanas (police stations) in Kolkata was prepared in 1785 for both police and municipal administration. Jorasanko was one of the 31 thanas then recorded.

Amongst the institutions in Jorasanko are – Adi Brahmo Samaj, the Jorasanko Bharati Natya Samaj, the Kalikata Haribhakti Pradayani Sabha, the Minerva Library and Oriental Seminary. The Oriental Seminary, founded in 1829, was one of the earliest privately-run, modern educational institutions in Kolkata. It was open to middle and lower middle-class Hindu boys only.

Rabindra Bharati University, the third university in Kolkata, was set up in 1962 in the Tagore family's house at Jorasanko, primarily as a centre for music and fine arts, but extended subsequently to arts and humanities.

In 1888, one of the 25 newly organized police section houses was located in Jorasanko.

Jorasanko was historically an important centre of the shell industry in Kolkata, but it has been on the decline in recent years.

Jorasanko is located on Rabindra Sarani (earlier Chitpore Road). Some people refer to the entire stretch through which Chitpore Road ran as Chitpore or Chitpur; that also includes Jorasanko.
