United Bank of India (UBI) was a public sector bank in India, headquartered in Kolkata, West Bengal. Established in 1950 through the amalgamation of four Bengal-based banks, it was nationalised by the Government of India in 1969. The bank operated as one of India's nationalised banks for several decades before being merged with Punjab National Bank, along with Oriental Bank of Commerce, with effect from 1 April 2020.

United Bank of India traced its origins to four commercial banks based in Bengal: the Comilla Banking Corporation (founded 1914), the Bengal Central Bank (1918), the Comilla Union Bank (1922), and the Hooghly Bank (1932). These institutions were established during the early twentieth century to serve the credit and deposit needs of communities in undivided Bengal, in a period when indigenous banking was expanding alongside colonial-era exchange banks.
In 1950, the four banks were amalgamated to form United Bank of India. The merger was intended to consolidate the financial position of the constituent banks, several of which had been affected by the Partition of Bengal in 1947 and the resulting disruption to their branch networks in East Pakistan.
On 19 July 1969, United Bank of India was among the fourteen major Indian commercial banks nationalised by the Government of India under the Banking Companies (Acquisition and Transfer of Undertakings) Act. Following nationalisation, the bank expanded its branch network significantly, particularly in eastern and north-eastern India, where it served as one of the lead banks for priority sector and rural lending.
The bank was traditionally strong in the eastern region of India, with a substantial branch presence in West Bengal, Assam, Tripura, Manipur and other north-eastern states, in addition to operations across the country. It was designated lead bank for several districts in this region. UBI offered retail banking, corporate banking, agricultural finance, and treasury services, and participated in government-sponsored schemes for financial inclusion.
United Bank of India came out with an initial public offering in 2010, listing its equity shares on Indian stock exchanges while the Government of India continued to hold a majority stake.
In August 2019, the Union Finance Ministry announced a major consolidation of public sector banks. Under this plan, United Bank of India and Oriental Bank of Commerce were to be amalgamated into Punjab National Bank. The merger took effect on 1 April 2020, creating the second-largest public sector bank in India by branch network and business at the time. With this amalgamation, United Bank of India ceased to exist as a separate legal entity, and its branches, employees, customers and assets were transferred to Punjab National Bank.
United Bank of India played a notable role in extending formal banking services in eastern and north-eastern India, regions that historically had lower banking penetration than other parts of the country. As a lead bank in several districts, it was associated with the implementation of priority sector lending norms, agricultural credit, and self-help group linkage programmes. Its dissolution in 2020 was part of a broader restructuring of the Indian public sector banking landscape aimed at creating fewer but larger banks.
