Source-derived summary

Than Phu Ying Ploypailin Jensen (Thai: พลอยไพลิน เจนเซน; RTGS: Phloiphailin Chensen; born February 12, 1981) is a member of the Thai royal family, a granddaughter of King Bhumibol Adulyadej of Thailand and a niece of King Vajiralongkorn of Thailand. She is the eldest offspring of Princess Ubolratana Rajakanya of Thailand. Ploypailin is not in the line of succession to the throne of Thailand as her mother relinquished her royal title when she married Ploypailin's American father, Peter Ladd Jensen.

Early life and education

Born in 1981 in San Diego, and known as Khun Ploypailin in Thailand, she is the grandchild of King Bhumibol Adulyadej and Queen Sirikit of Thailand and the eldest daughter of Princess Ubol Ratana. Her given name was proposed by her aunt, Princess Maha Chakri Sirindhorn.

Ploypailin had a younger brother, Poom Jensen (1983–2004), and a younger sister, Sirikitiya Jensen (b. 1985).

Ploypailin attended the Purcell School, England. She received a bachelor's degree with honors in cognitive psychology from the University of California, San Diego in 2003 and an MBA degree from the MIT Sloan School of Management in 2007.

Personal life

As a pianist, she has given performances around the world, including at the Sydney Opera House, and other venues in Europe and Japan.

Editorial summary

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1981, 1983, 2004, 1985—that can be checked directly. The linked authority record independently contributes the date 1981-02-13. For this dossier, Ploypailin, Jensen and Thai is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “thai royal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q4385933. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1981, 1983, 2004 and 1985.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
