The Diocese of Calcutta of the Church of North India was established in 1813 as part of the Church of England. It is led by the Bishop of Calcutta and the first bishop was Thomas Middleton (1814–1822) and the second Reginald Heber (1823–1826). Under the sixth bishop Daniel Wilson (1832–1858) the see was made Metropolitan (though not made an Archbishopric) when two more dioceses in India came into being (Madras, 1835, and Bombay, 1837).
Calcutta was made a metropolitan see by letters patent on 10 October 1835 and in 1930 was included in the Church of India, Burma and Ceylon (from 1948 the Church of India, Pakistan, Burma, and Ceylon) until 1970. In 1970, the Church of the Province of Myanmar, Church of Ceylon and the Church of Pakistan were separated from the province.
The Anglican dioceses in Northern India merged with the United Church of Northern India (Congregationalist and Presbyterian), the Methodist Church (British and Australian Conferences), the Council of Baptist Churches in Northern India, the Church of the Brethren in India, and the Disciples of Christ to form the Church of North India in the same year.
The diocese currently has jurisdiction over the corporation limits of Kolkata and the Districts of Hooghly & Howrah in the state of West Bengal. The bishop's seat (cathedra) is located in the city of Kolkata at St. Paul's Cathedral. The current bishop is the Ashoke Biswas.
