Meaning & Origin
A unisex given name. A diminutive of the male given name Oliver, from French [in turn from Latin, in turn from Germanic]. A female given name. A diminutive of the female given names Olivia or Olive, from Latin [in turn from Etruscan, in turn from Greek]. A diminutive of the female given name Olwen, from Welsh.
Ollie is a boy's and girl's baby name of French origin, a diminutive of Oliver, from the Old French Olivier, from the Latin olivarius (olive tree planter) or possibly the Old Norse Aleifr, meaning "olive tree" or "ancestor's legacy."
With over 17,000 U.S. births, Ollie has established itself as a genuine first name beyond its nickname origins. In England, it consistently ranks among the top 10 boys' names, and in the United States it carries the same warm, friendly charm that has made the Oliver family of names perennially beloved.
