Pleumjit Thinkaow (Thai: ปลื้มจิตร์ ถินขาว; rtgs: Pluemchit Thinkhao; born 9 November 1983) is a Thai volleyball player.
She is a member of the Thailand women's volleyball team. Her international debut was at the 21st SEA Games in Malaysia.
Pleumjit grew up in a sport-loving family in Angthong (a province about 100 km. north of Bangkok), having an elder brother. Her parents are civil servants. Before she started playing volleyball, she had been rather into table tennis. She switched to volleyball following her father’s advice that volleyball was more fun and more likely to become popular. Afterwards, a volleyball coach of Bodindecha (Sing Singhaseni) School in Bangkok was so impressed by her playing that he brought her to the school during her high-school level. At first, she did not play as a middle blocker but an outside hitter.
Pleumjit was first capped for the national junior team in 2000. A year later, she was chosen to join the national team. She went to play professional volleyball overseas for the first time in China for a month when she was 20 years old.
Pleumjit got her bachelor's degree and master's degree in Business Administration from Rattana Bundit University Bangkok.
Thinkaow won the 2013–14 Azerbaijani Super League Bronze Medal 3-0 to Azerrail Baku and she won the Best Spiker award.
