Renee Li-Yen Lim (born 1978/1979 in Perth, Australia) is an Australian actress, television presenter and medical doctor.
Lim was born in Perth, Western Australia to Chinese-Malaysian parents who had migrated from Malaysia to Australia in the 1970s. When she was five years old, her parents divorced; Lim was primarily raised by her single father, and her mother moved to Malaysia and remarried a Peranakan man. Lim would often travel to Malaysia, where she had family other than her mother, to visit her mother. Lim's father later remarried and had a son with his new wife when she was 12 years old.
Lim graduated as the dux of her high school, Hampton Senior High School. Few from Lim's high school pursued tertiary studies, and she had initially intended to "be a doctor on weekdays, a lawyer on weekends, an actor on the holidays and a dancer at night".
At 17 years old, Lim moved to Sydney, New South Wales to commence medical studies at the University of New South Wales, graduating with a Bachelor of Medicine, Bachelor of Surgery in 2001.
In 2000, Lim co-directed the University of New South Wales Medical Revue, American Booty (an homage to the 1999 film American Beauty), alongside Keith Lim and Jason Appleby. Also during her university studies, Lim co-authored two academic articles.
Lim is a physician, mostly working in part-time, locum posts in emergency medicine, geriatrics, and palliative care departments, and a clinical lecturer at the University of Sydney's Northern Clinical School. She is the Director of Programs at the Pam McLean Centre, an organisation that develops communication training for medical professionals.
