Big Time Wrestling – also known as the American Wrestling Alliance (AWA) or National All-Star Wrestling – was a professional wrestling promotion headquartered in San Francisco, California in the United States. Founded by "Professor" Roy Shire (1921–1992) in 1960, the promotion emerged as one of the most profitable in the United States thanks to its "red hot angles" and "good TV". The promotion's heartland was the San Francisco Bay Area, with the Cow Palace as its core venue, but it also ran regular shows in cities including Fresno, Las Vegas, Oakland, San Jose, and Sacramento. Shire folded the promotion in 1981.
