Old Stock American (also known as Pioneer Stock, Founding Stock or Colonial Stock) is a colloquial name for Americans who are descended from the original settlers of the Thirteen Colonies. Historically, Old Stock Americans have been mainly Protestants from Northwestern Europe whose ancestors emigrated to British America in the 17th and 18th centuries.

In the statistical terminology of the U.S. Census Bureau, Americans from the third-, fourth-, and fifth-generations are labelled "Old Stock" unless they are Afro-Americans, Asian Americans, or American Indians.
