Sandra Anne Brondello is an Australian women's basketball coach, and the current head coach of the New York Liberty of the WNBA. Brondello played in Australia, Germany and the WNBA before retiring to become a coach. The 5 ft 7 in (1.70 m) Brondello is one of Australia's all-time best shooting guards. She played on Australia's "Opals" national team at four Summer Olympics, and won three medals (one bronze, two silvers). She attended the Australian Institute of Sport in 1986–1987, and was inducted to the Australian Basketball Hall of Fame in 2010.
In 2005, Brondello was named an assistant coach of the San Antonio Silver Stars. She was promoted to head coach in February 2010.

Brondello and her husband, associate head coach Olaf Lange, were fired by the Silver Stars in September 2010. Brondello finished her only season as head coach with a 14–20 record, third best in the Western Conference. They were eliminated in the first round of the playoffs by Phoenix two games to none.
