Yemaek or Yamaek (Korean pronunciation: [jemɛk]) were an ethnic group who dwelt in Manchuria and the Korean Peninsula. They had ancestral ties to various Korean kingdoms including Gojoseon, Gori (고리; 藁離), Buyeo, Goguryeo, Baekje, Okjeo, Dongye, Yangmaek (양맥; 梁貊) and Sosumaek (소수맥; 小水貊), and is believed to be one of the ancient tribes that were formed into the Tungusic peoples.
Yemaek is believed to be a combination of Ye (濊·穢·薉) and Maek (貊·貉) people of two neighboring cultures. The main culture is the Xitunshan culture (西团山文化). He Qiutao (何秋涛) said Ye is the short name of Buyeo. Dongye first appears in history as a vassal state of Gojoseon until its fall to China in 108 BCE. It was known as the Huiyetou (穢邪頭) state in Shuowen Jiezi. It later became a vassal of the increasingly powerful Goguryeo. According to the Chinese Records of Three Kingdoms, Ye worshiped tigers, whereas according to Erya (爾雅), Maek means bears. Gomnaru, the capital of Baekje, also means the "bear port". Historians suggest tigers and bears may have been totems worshiped by Ye and Maek tribes.
Several history books suggest Gojoseon, the first Korean kingdom in history, was established by Yemaek.
- In Dangun's ancestry legend of Gojoseon recorded in Samguk Yusa, a tiger and a bear prayed to Hwanung that they may become human but had to stay in a cave eating only garlic and mugwort, and while the tiger shortly gave up and left the cave, the bear remained and after 21 days was transformed into a woman who later married Hwanung and then gave birth to Dangun Wanggeom, which is believed to symbolize combination of Ye and Maek tribes into one Yemaek tribe.
- Tombstone of Yeon Namsan (연남산) found in Luoyang says Yeon, son of Goguryeo's leader Yeon Gaesomun, is a Joseon person.
- Gojoseon is called "Yemaek Joseon" in the Chinese Records of the Grand Historian, which says Yemaek Joseon bordered on Xiongnu around 200 BC.
According to Samguk Sagi, Silla was established as a confederacy of six clans composed of Joseon refugees, and the Royal Seal of Ye (예왕지인; 濊王之印), previously used by Buyeo's kings, was found in Silla in 19 AD and presented for King Namhae of Silla.
