The peninsula's names, in Korean, Chinese and Japanese, all share the same origin, that being Joseon, the old name of Korea under the Joseon Dynasty and Gojoseon even longer before that. In North Korea's standard language, the peninsula is called Chosŏn Pando (Korean: 조선반도; Hanja: 朝鮮半島; RR: Joseon Bando), while in China, as well as in Singapore and Malaysia (where Chinese is a common language), it is called Cháoxiǎn Bàndǎo (朝鲜半岛/朝鮮半島).In Japan, it is either Chōsenhantō (Kanji: 朝鮮半島 / Hiragana: ちょうせんはんとう) or Kanhantō (South Korean-specific only) (Kanji: 韓半島 / Hiragana: かんはんとう). In Vietnam, it is called Bán đảo Triều Tiên. Meanwhile, in South Korea, it is called Hanbando (Korean: 한반도; Hanja: 韓半島), referring to the Samhan, specifically the Three Kingdoms of Korea, not the ancient confederacies in the southern Korean Peninsula. They both use "Korea" as part of their official English names, which is a name that comes from the Goryeo (or Koryŏ, in North Korea) dynasty (고려; 高麗).
