Leroy Chiao (born August 28, 1960) is an American engineer, former NASA astronaut, entrepreneur, motivational speaker, and engineering consultant. Chiao flew on three Space Shuttle flights, and was the commander of Expedition 10, where he lived on board the International Space Station from October 13, 2004 to April 24, 2005. He is also a co-author and researcher for the Advanced Diagnostic Ultrasound in Microgravity project.

Chiao was born in Milwaukee, Wisconsin and raised in Danville, California. He is the son of immigrant Chinese parents. Chiao graduated from Monte Vista High School in Danville in 1978. In 1983, he earned a B.S. in chemical engineering from the University of California, Berkeley. He later earned an M.S. and a Ph.D. in chemical engineering from the University of California, Santa Barbara in 1985 and 1987, respectively.

Chiao’s parents were both chemical engineers who immigrated to Milwaukee from Taiwan in the late 1950s for graduate school. They wanted their children to retain their Asian values, but also chose to assimilate their son and his two sisters into the American culture, urging them to be more assertive in society. Stressing a science education, his parents encouraged him to follow their lead and become an engineer. Chiao's Aviator call sign is "Shandong".
