Sri Suriyendra (Thai: ศรีสุริเยนทร, RTGS: Si Suriyen, Śrī Suriyendrā; 1767–1836) was the queen of Siam, wife of Phutthaloetla Naphalai, who was her cousin, and mother of Mongkut and Pinklao.

She was later named, upon the coronation of her son Mongkut, as Krom Somdet Phra Sri Suriyendramat.

Princess Bunrot lived with her mother in the Grand Palace and grew up with her maternal female cousins, the daughters of Phutthayotfa Chulalok.

Princess Bunrot had an affair with her cousin, Prince Itsarasunthon, son and heir apparent to King Phutthayotfa Chulalok.

In 1801, the King discovered the princess' four-month pregnancy and banished her from the Grand Palace to live with her brother Prince Thepharirak.
