Rosalind Chao ( /ˈrɒzəlɪnd ˈtʃaʊ/; born September 23, 1959 (1959-09-23)) is a Chinese American actress. Chao's most prolific roles have been as a star of CBS' AfterMASH portraying South Korean refugee Soon-Lee Klinger for both seasons, and the recurring character Keiko O'Brien with 27 appearances on the syndicated science fiction series Star Trek: The Next Generation and Star Trek: Deep Space Nine.
Chao is married to voice actor Simon Templeman.
Born in Anaheim, California as a first-generation Californian of Chinese descent, Chao's parents ran a successful Chinese American pancake restaurant, Chao's, across the street from Disneyland, and employed her there from an early age. After moving from Garden Grove to Villa Park, California, Chao was enrolled at Marywood, an all-girls school where she was the only non-Caucasian student. She graduated from Pomona College in 1978.
Chao's parents were instrumental in her decision to pursue acting; she began at the age of five in a California-based Peking opera traveling company at the instigation of her parents who were already heavily involved, and during the summers they sent her to Taiwan to further develop her acting. She later performed in television commercials and guest starred on TV series in her teenage years. Her first acting role was in the CBS sitcom Here's Lucy, but she was first noticed performing in another CBS sitcom: 1972's short-lived Anna and the King as the eponymous king's (Yul Brynner) eldest daughter.
