Prince Dipangkorn Rasmijoti Sirivibulyarajakumar (born 29 April 2005; Thai: ????????????????; RTGS: Thipangkon Ratsamichot; Thai pronunciation: [t?i?pa?k??n rátsà mi?t??ô?t]) is a member of the country's Chakri dynasty and heir presumptive to the throne of Thailand.
He is the fifth son and seventh and youngest child of King Vajiralongkorn; his mother is Srirasmi Suwadee, the king's third legal wife.
His father also has a daughter by his first wife, and five children (four sons and a daughter) by his second wife; all the children of the second wife were born before the then-Crown Prince married their mother but were legitimised by their marriage.
After the Crown Prince divorced his second wife in 1996, he disowned their four sons.
Thus, Dipangkorn is the only recognised son of the king.
