Pauline Dy Phon ប៉ូលីន ឌី ផុន nee Tan (1933, Krav, Kompong Speu Province, Cambodia -21 May 2010) was a Cambodian botanist specialized in the flora of Southeast Asia.

After graduating from the Paris Faculty of Sciences in 1959, Pauline Dy Phon taught at Phnom Penh Lycée Sisowath before becoming a teacher and researcher with the University of Phnom Penh until 1975. She had obtained her doctorate in botanic from Toulouse University in 1969.

After surviving the Khmer Rouge regime, transiting through the Khao I Dang refugee camp and escaping to France -- her only written account of the Khmer Rouge period, published in 1982, was a study of “plants in the Khmer diet in normal times and in times of famine” --, she worked at the Botanical Laboratory of the Musée d'Histoire Naturelle (National Museum of Natural History), identifying and classifying plants of Cambodia and Indochina. One of the few women botanists then, she was awarded for her discovery of five new species of Papilionaceae, Euchresta Bennet, Gueldenstaedtia Fischer, Medicago Linné, Parochetus Buchanan Hamilton and Tifidacanthus Merril.

In their Historical Dictionary of Cambodia [n 43 in Aseania Historical Dictionaries series, The Scarecrow Press, Lanham (MD) & Oxford, 2003), Justin Corfield and Laura Summers mention Pauline only in the entry dedicated to her husband: "DY PHON (1932- ). A dental surgeon, he studied medicine at the Faculty of Medicine in Paris and married Tan Pauline, who graduated at the same time in Natural Sciences from the Faculty of Science in Paris, both returning to Cambodia in 1959. He became head of the dental surgery section of the Khmer-Soviet Hospital. In 1970 Dy Phon slipped out of Phnom Penh, rallied to the National United Front of Kampuchea and signed the 1971 Declaration of Patriotic Intellectuals. After April 1975 he worked once again at the April 17th Hospital (the renamed Khmer-Soviet Hospital), but as purges of the administration widened, he fell under suspicion of counter-revolutionary activities, and was arrested on 10 December 1978 and taken to Tuol Sieng. He was still there on 7 January 1979 when the Vietnamese freed him."

Back to Cambodia again from 1994, Pauline Dy Phon published in 2000 a 915-page Dictionary of plants used in Cambodia (Dictionnaire des plantes utilisées au Cambodge), with entries in French, English and Khmer. The year before, she had co-authored with Bernard Rollet the Lexique des Arbres Forestiers du Cambodge (EFEO Publications, 1999).
