The Ramadanids, also known as the Ramadanid dynasty, Emirate of Ramadan, Beylik of Adana, and Ramadanid principality (Modern Turkish: Ramazanoğulları, Ramazan and Ramazanoğulları Beyliği), was one of the Anatolian beyliks. Its capital was in Adana. It was one of the frontier emirates established by Oghuz Turkish clans after the decline of Seljuk Sultanate of Rum.

Because of the Mongol invasion Turkmens started migrating into Anatolia in great numbers. The Mameluk sultan gave them the right to settle from Antioch to Gaza. In return Turkmens became a great help in battles against Crusaders and Mongols.

As a result of Abu Sa'id Bahadur Khan's death, Turkmens turned their eyes on Cilicia and they started to settle the provinces which they captured. With the help of the Mameluks in 1360 Adana and Tarsus were captured, leaving only a few castles to the Armenians. Ramazan Bey, from the Yuregir clan of Oghuz Turks had founded the emirate and made Elbistan the capital. However, after the conquest of Elbistan by the Emirate of Dulkadir, the capital was moved to Adana.

In 1375, Ramadanids destroyed the Armenian Kingdom of Cilicia in the name of the Mamluk sultan of Egypt, this became the core territory of the Ramadanids.
