Teresa (also Theresa, Therese; French: Thérèse) is a feminine given name.
It originates in the Iberian Peninsula in late antiquity.
Another origin of the name is from Latin word "Terra" which means earth.
Its popularity outside of Iberia increased because of saint Teresa of Ávila, and more recently Thérèse of Lisieux and Mother Teresa.
Spelled "Teresa," it was the 580th most popular name for girls born in 2008, down from 206th in 1992 (it ranked 81st in 1950, and 220th in 1900).
