Lizzie is the classic English pet form of Elizabeth, the Hebrew name Elisheva, which means "God is my oath" or "God is abundance". It was a hugely common nickname in Victorian times and is still used on its own, as for Lizzie McGuire, the Disney character of the early 2000s. As a given name in the United States, Lizzie peaked at number 1796 in 2003 and ranks number 2145 in 2025.
