This is a survey of the postage stamps and postal history of India.

Indian postal systems for efficient military and governmental communications had developed long before the arrival of Europeans. When the Portuguese, Dutch, French, Danish and British displaced The Marathas who had already defeated the Mughals, their postal systems existed alongside those of many somewhat independent states. The British East India Company gradually displaced other powers and brought into existence a British administrative system over most of India, with a need to establish and maintain both official and commercial mail systems.

Although the Indian Post Office was established in 1837, Asia's first adhesive stamp, the Scinde Dawk, was introduced in 1852 by Sir Bartle Frere, the British East India Company's administrator of the province of Sind. The Indian postal system developed into an extensive, dependable and robust network providing connectivity to almost all parts of India, Burma, the Straits Settlements and other areas controlled by the British East India Company (EIC). Based on the model postal system introduced in England by the reformer, Rowland Hill, efficient postal services were provided at a low cost and enabled the smooth commercial, military and administrative functioning of the EIC and its successor, the British Raj. The Imperial Posts co-existed with the several postal systems maintained by various Indian states, some of which produced stamps for use within their respective dominions, while British Indian postage stamps were required for sending mail beyond the boundaries of these states. Telegraphy and telephony made their appearance as part of the Posts before becoming separate departments. After the Independence of India in 1947, the Indian postal service continues to function on a countrywide basis and provides many valuable, low cost services to the public of India.
