Terri is an American female given name of American origin. It is often used as a diminutive form of Teresa, a name derived from the Latin word 'tértius', meaning 'third'. Terri was most popular in the United States during the mid-20th century and is now considered somewhat vintage. Notable individuals named Terri include Terri Irwin, an Australian naturalist, television personality, and conservationist, and Terri Huckaby, a retired American basketball player who won three Olympic gold medals with the U.S. women's national team.
The name Terri saw a significant rise in popularity from the late 1940s to the mid-1960s, peaking around 1963 with 36 births. However, it started declining steadily thereafter, with only single-digit numbers of births per year since the early 1970s, and has been quite rare in recent years, with just a handful of Terri births annually between 1992 and 2008.
