There are various names of Korea in use today that are all derived from those of ancient Koreanic kingdoms and dynasties. The choice of name often depends on the language, whether the user is referring to either or both modern Korean countries, and even the user's political views on the Korean conflict.

The Korean conflict is an ongoing conflict based on the division of Korea between North Korea and South Korea, both of which claim to be the sole legitimate government of all of Korea. During the Cold War, North Korea was backed by the Soviet Union, China, and other allies, while South Korea was backed by the United States, United Kingdom, and other Western allies.
