The Sayyid dynasty was the fourth dynasty of the Delhi Sultanate from 1414 to 1451. They succeeded the Tughlaq dynasty and ruled that sultanate until they were displaced by the Lodi dynasty.

They claimed to belong to the family of Sayyids or the descendants of the Prophet Muhammad through his daughter Fatima and son-in-law and cousin Ali who belonged to the Banu Hashim Clan of the Quraish Tribe. After Timur sacked Delhi and ended the Delhi Sultanate in 1398, he appointed these Sayyids as the governor of Delhi. Their 37-year period of dominance witnessed the rule of four different members of the dynasty.

The dynasty was established by Sayyid Khizr Khan, deputised by Timur to be the governor of Multan (Punjab). Khizr Khan took Delhi from Daulat Khan Lodi on May 28, 1414 and founded the Sayyid dynasty. But he did not take up the title of sultan and nominally, continued to be a Rayat-i-Ala (vassal) of the Timurids, initially of Timur and after his death, his successor Shah Rukh, grandson of Timur. Khizer Khan was succeeded by his son Sayyid Mubarrak Khan after his death on May 20, 1421, who styled himself as Muizz-ud-Din Mubarak Shah in his coins. A detailed account of his reign is available in the Tarikh-i-Mubarak Shahi written by Yahya-bin-Ahmad Sirhindi. After the death of Mubarak Shah, his nephew Sayyid Muhammad Khan ascended the throne and styled himself as Sultan Muhammad Shah. Just before his death, he called his son Sayyid Ala-ud-Din from Badaun and nominated him as his successor.
