Leo Suryadinata (born Liauw Kian-Djoe [or Liao Jianyu; 廖建裕] in Jakarta, 21 February 1941) is an Indonesian-born Singaporean[2] sinologist.

Suryadinata was born Liauw Kian-Djoe (also written Liao Jianyu) in Batavia, Netherlands Indies (today Jakarta, Indonesia) to a Chinese Indonesian business family.

Suryadinata later attended Nanyang University in Singapore, where he graduated in 1962 with a bachelor of arts degree in Chinese and Southeast Asian literature.

Aimee Dawis of The Jakarta Post writes that "anyone studying the ethnic Chinese in Indonesia is bound to encounter Leo Suryadinata's works.

"[3] In 2008, Suryadinata (together with German researcher Mary F. Somers) received the Nabil Award for contributions to Indonesian ethnic integration.
