Endeavour Sports High School is a government-funded co-educational comprehensive and specialist secondary day school, with speciality in sports, located in Caringbah, a southern suburb of Sydney, New South Wales, Australia.

A sports school is a type of educational institution for children that originated in the Soviet Union. Sports schools were the basis of the powerful system of physical culture (fitness) and sports education in the USSR and the Eastern Bloc, particularly East Germany. The main features of this system remain in the system of sports education in Russia and other post-Soviet states, and also became the basis of similar systems in other countries, one of the most powerful ones at the present time being that of the People's Republic of China. Many legendary athletes, such as Nikolai Andrianov, Nellie Kim, Alexander Popov, Viktor Krovopuskov, Vladislav Tretiak, Valeri Kharlamov, Anatoly Alyabyev and Sergey Bubka started their path to Olympic success from Soviet sports schools. They are also found in Asia, in countries such as Singapore, Malaysia and Australia.
