Dhirendranath Datta (2 November 1886 – disappeared 29 March 1971)[1] was a Bengali lawyer and politician from East Bengal who was a member of the 1st Constituent Assembly of Pakistan.

[2] Datta was born in an Aristocrat Kayastha Family on 2 November 1886 in Ramrail, in Brahmanbaria District,[3] Bengal Province (in today's Bangladesh).

Datta firmly opposed the creation of Pakistan and partition of India on religious lines; but when it became clear that partition of Bengal was inevitable and that his home district of Comilla would be in the new Muslim majority state, he opted to remain in East Bengal (unlike many other Hindu leaders), and as a result, was invited to be part of the constitutional committee to draft the legislative framework of the new country before the actual independence of Pakistan.

Datta continued to represent his constituency as a Hindu member of the renamed Pakistan National Congress (seats were allocated by a quota according to religion).

In 1954, he moved an adjournment motion against the declaration of Governor's Rule in East Pakistan, and was seen as the de facto face of protest and democracy.
