Kimberly is a gender-neutral name of Old English origin. It means "Cyneburg's field," while Cyneburg was a name meaning "royal forest." You might be most familiar with Kimberly as a girl's name, but masculine use of the name can be traced back to the Boer War when soldiers were fighting in the town of Kimberley in South Africa. This name was at its most popular in the 60s, 70s, and 80s, with some of the most famous Kimberlys from this time including Kim Kardashian and Lil' Kim.
