巴赫曼尼苏丹国（1347年-1518年 泰卢固语：బహుమనీ సామ్రాజ్యము）بہمانی سلطانت)是处于印度德干高原的古代苏丹国。

1347年，阿富汗君主阿拉丁·哈桑·巴赫曼沙阿摆脱了德里苏丹的束缚，建都古尔伯加。1425年移都比德尔。1518年巴赫曼尼苏丹国的统治瓦解，取而代之的是五个独立的苏丹国，所谓的德干苏丹国：比德尔、比贾布尔、艾哈迈德讷格尔、毕拉尔以及果尔贡德。五个苏丹国纷争不休，战乱不断。最后莫卧儿入侵，各苏丹国逐一沦陷。

The Bahmani Sultanate (also called the Bahmanid Empire or Bahmani Kingdom) was a Muslim state of the Deccan in South India and one of the great medieval Indian kingdoms. Bahmanid Sultanate was the first independent Islamic Kingdom in South India.

The empire was established by Turkic general Ala-ud-Din Bahman Shah after revolting against the Delhi Sultanate of Muhammad bin Tughlaq. Nazir Uddin Ismail Shah who had revolted against the Delhi Sultanate stepped down on that day in favour of Bahman Shah. His revolt was successful, and he established an independent state on the Deccan within the Delhi Sultanate's southern provinces. The Bahmani capital was Ahsanabad (Gulbarga) between 1347 and 1425 when it was moved to Muhammadabad (Bidar). The Bahmani contested the control of the Deccan with the Vijayanagara Empire to the south. The sultanate reached the peak of its power during the vizierate (1466–1481) of Mahmud Gawan. The south Indian Emperor Krishnadevaraya of the Vijayanagara Empire defeated the last remnant of Bahmani Sultanate power after which the Bahmani Sultanate collapsed. After 1518 the sultanate broke up into five states: Nizamshahi of Ahmednagar, Qutb Shahi of Golconda (Hyderabad), Baridshahi of Bidar, Imadshahi of Berar, Adilshahi of Bijapur. They are collectively known as the "Deccan Sultanates".
