勒克瑙协定(Lucknow Pact)是指印度国大党和全印穆斯林联盟之间签署的协议。1916年，国大党成员穆罕默德·阿里·真纳和穆斯林联盟商议，迫使大英帝国政府给予印度更多自由，确保印度人有更多管理国家的权力。对穆斯林联盟联盟而言，是政策的转折点，该协定保证了穆斯林联盟的利益，以维护英国在印度的统治。孟加拉地区的划分遭到非议以后，穆斯林联盟的立场受到质疑，此时真纳接近该政党，成为该协定的的设计者；尽管真纳为国大党成员，后来成为穆斯林联盟的领导人。

勒克瑙协定的签署，也是国大党二大主要派别即激进派和温和派走向合作的标志。

Lucknow Pact refers to an agreement reached between the Indian National Congress and the Muslim League at the joint session of both the parties, held in Lucknow, in the year 1916. Muhammad Ali Jinnah, then a member of the Congress as well as the League, made both the parties reach an agreement to pressure the British government to adopt a more liberal approach to India and give Indians more authority to run their country, besides safeguarding basic Muslim demands. After the unpopular partition of Bengal, Jinnah approached the League to make it more popular among the Muslim masses. Jinnah himself was the mastermind and architect of this pact. Due to the reconciliation brought about by Jinnah between the Congress and the League, the Nightingale of India, Sarojini Naidu, gave him the title of “the Ambassador of Hindu-Muslim Unity”.
