Korean Australians are Australian citizens who trace their Korean ancestry and identify themselves as an immigrant to or a descendant born in Australia.

Koreans are an East Asian ethnic group native to Korea. The majority of Koreans live in the two Korean nation states of North and South Korea, which are collectively referred to as Korea. As of 2021, an estimated 7.3 million ethnic Koreans resided outside of Korea. Koreans are also an officially recognised ethnic minority in other several Continental and East Asian countries, including China, Japan, Kazakhstan, Russia, and Uzbekistan. Outside of Continental and East Asia, sizeable Korean communities have formed in Germany, the United Kingdom, France, the United States, Canada, Australia, and New Zealand.
