The New England Colonies of British America included Connecticut Colony, the Colony of Rhode Island and Providence Plantations, Massachusetts Bay Colony, Plymouth Colony, and the Province of New Hampshire, as well as a few smaller short-lived colonies. The New England colonies were part of the Thirteen Colonies and eventually became five of the six states in New England, with Plymouth Colony absorbed into Massachusetts and Maine separating from it.

British America comprised the colonial territories of the English Empire, and the successor British Empire, in the Americas from 1607 to 1783. These colonies were formally known as British America and the British West Indies immediately prior to thirteen of the colonies seceding in the American Revolutionary War (1775–1783) and forming the United States of America.
