Michelle Hsiao Au () is an American anesthesiologist and politician from Georgia. Au has served in the Georgia House of Representatives as a Democratic member for District 50 since 2023. Au previously represented the 48th District in the Georgia State Senate and was the first Asian American elected to that body. In December 2021, Au announced that she would not be running for re-election in Senate District 48 but instead would run for election in Georgia state House District 50 due to the Republican controlled state legislature re-drawing her district.
In 2011, Au published her book This Won't Hurt a Bit (and Other White Lies), which according to a review, "exposes the reality of medical education and the irony within the practice of medicine that physicians are human, but our patients want us to be more".
Au was born to Chinese-American immigrants, both physicians, in New York City. She graduated from Hunter College High School in 1995, from Wellesley College in 1999 with a B.A. in Psychobiology, M.D. in 2003 and a Master of Public Health in 2019 from Columbia University.
Au lives in Duluth, Georgia, and has three children.
