Niramon Ounprom (Thai: ????? ???????; RTGS: Niramon Unphrom; born 26 or 28 January 1985) is a former Thai nurse, army officer, and member of the Thai royal court.
She was named concubine of Crown Prince Vajiralongkorn of Thailand, who granted her several military ranks and positions, including the noble name of Sineenat Wongvajirapakdi (Thai: ??????? ???????????????; RTGS: Sininat Wongwachiraphak).
After Prince Vajiralalongkorn ascended the throne as King Rama X, he appointed her as his Royal Noble Consort, giving her the noble title of Chao Khun Phra Sineenat Bilaskalayani (Thai: ????????????????? ????????????; RTGS: Sininat Philatkanlayani) in July 2019.
She was the first woman to be a concubine of the King of Thailand in almost a century, because the previous kings were monogamous.
However, in October 2019, King Rama X issued a royal edict stripping her of all her government, military, and noble ranks, positions, and titles, as well as royal decorations, citing her conflict with and disrespectful conduct towards his wife, Queen Suthida.
