The Bunnag Family or House of Bunnag (Thai: บุนนาค; RTGSBunnak) is a Siamese aristocratic clan of Mon-Persian descent influential during the late Ayutthaya kingdom and early Rattanakosin period. The family was favored by Chakri monarchs.

Three of the four Somdet Chao Phraya came from the Bunnag family — Dit, styled Somdet Chao Phraya Borom Maha Prayurawongse; his younger brother Tat, styled Somdet Chao Phraya Borom Maha Pichaiyat; the eldest son Chuang, styled Somdet Chao Phraya Borom Sri Suriwongse. They have played key roles in government and foreign relations.
