Chamorros are Micronesians, who are the native peoples of Guam and Northern Marianas.

Chamorros were believed to be Malay peoples whose ancestors came from Indonesia, Malaysia, and Philippines to Guam and Marianas Islands in 2000 BC. They resemble the peoples, languages, music, and cultures of these countries. They were expert seamen and skilled craftsmen familiar with intricate weaving and detailed pottery making and who built unique houses and canoes suited to this region of the world. They impart the matriarchal authority.

The present-day Chamorros are of mixed races. They are a mixture of Eurasians — wherein Asians include Pacific Islanders — Africans, and Native Americans. They do not only include Malays, Indonesians, and Filipinos, but also mixed with Chinese, Japanese, Koreans, Vietnamese, Spanish, Americans (including Caucasian, Native American, and African), and other Pacific Islanders — especially Polynesians (also Hawaiians) and Micronesians. Chamorro language is included in Malayo-Polynesian languages of the Austronesian family. It borrowed many words from foreign languages. Most words were derived from Spanish, American English, and Japanese, with a few from other Asian, like Chinese, and Austronesian languages, like Hawaiian.
