Meaning & Origin
Bettye is a girl's and boy's baby name of Hebrew origin, a stylized spelling variant of Betty, itself a diminutive of Elizabeth, meaning 'my God is an oath' or 'my God is abundance.' The -ye ending was a mid-20th century flourish to give the name extra distinction.
This spelling appeared particularly in African-American communities from the 1930s through the 1960s. Civil rights activist Bettye Lane and others gave the name a strong, purposeful character.
