Eastern Mongols may refer to:

• Buryats, Khalkhas and Inner Mongolians settling in Eastern Greater Mongolia (as opposed to Oirats (= Western Mongols))
• Khorchin and Kharchin Mongols who mainly settle in south-western Manchuria as farmers and herder-farmers and speak Eastern Mongolian dialects (as opposed to Khalkha and Chahar Mongols who live as pure herders in their west and speak Central Mongolian dialects)
