Hmong Americans (RPA: Hmoob Mes Kas, Pahawh Hmong: "𖬌𖬣𖬵 𖬉𖬲𖬦 𖬗𖬲") are Americans of Hmong ancestry. Many Hmong Americans immigrated to the United States as refugees in the late 1970s. Over half of the Hmong population from Laos left the country, or attempted to leave, in 1975, at the culmination of the Laotian Civil War.
