Meaning & Origin
A diminutive of the male given names Alexander, Sander, Alasdair, Sandeep, Sanford, or Santiago.
Sandy is a girl's and boy's baby name most commonly used as a diminutive of Sandra or Alexandra, from the Greek Alexandros, meaning 'defender of men.' It also carries associations with the color and texture of sand — relaxed, sunny, beach-adjacent.
Sandy had its golden era in the 1950s and 1960s, perfectly embodied by Sandy Olsson, Olivia Newton-John's iconic character in Grease (1978) — wholesome on the surface, with a spark underneath. As a standalone name rather than a nickname, Sandy peaked around that same cultural moment and has since settled into nostalgic charm.
