The Pontianak Kadriyah Sultanate (Jawi: کسلطانن قدرية ڤنتيانق‎ ) was a Malay state that existed on the western coast of the island of Borneo from the late 18th century until its disestablishment in 1950.

The Pontianak Sultanate was founded in 1771 by explorers from Hadhramaut led by al-Sayyid Syarif Abdurrahman al-Kadrie, a son of a Hadramaut Arab cleric from the Mempawah Kingdom and descendant of Imam Ali al-Uraidhi ibn Ja'far al-Sadiq, on Wednesday, 23 October 1771 (14 Rajab 1185 H) which was marked by clearing the forest at the junction of the Landak River, Kapuas Kecil River, and Kapuas Besar River to build a hall and house as a residence.

Palm was later replaced by Wolter Markus Stuart who acted as Resident van Borneo's Wester Afdeling I (1779-1784) with a seat in Pontianak.

Subsequently, Syarif Kasim Alkadrie (1808-1819) ascended the throne to become Sultan of Pontianak in place of his father.

During the reign of Sultan Syarif Usman, many beneficial policies were issued by him, including by continuing the construction project of the Jami' Mosque in 1821 and the expansion of Kadriyah Palace in 1855.

The era of Sultan Syarif Muhammad's reign faded quickly with the arrival of the Imperial Japanese army to Pontianak in 1942.

The Japanese had actually suspected that in West Kalimantan there were plots consisting of scholars, nobles, kings, sultans, community leaders, Chinese people, and officials.

Not only making arrests, the Japanese also tortured and mass murdered thousands of residents of Pontianak and its surroundings.

The murder of Sultan Syarif Muhammad and the arbitrary actions of the Japanese were one of the main factors in the Dayak Desa War.

Besides being the Chairman of the Federal Consultative Assembly (Bijeenkomst voor Federaal Overleg / BFO) in 1949, he was also Minister of State Zonder Porto Folio in the Cabinet of the United Republic of Indonesia.

After the dissolution of the Republic of Indonesia on 17 August 1950, the Pontianak Sultanate area became part of West Kalimantan Province.

However, on 15 January 2004, the Kadriyah Palace nobles appointed Syarif Abubakar Alkadrie as the 8th Sultan of Pontianak.
