Chardonnay is a female given name. The name derives from Chardonnay wine, which originated in the village of Chardonnay in France. The name originally meant "thistle-covered place." (Evans, 2006)
In the United Kingdom, the name became fashionable due to the character Chardonnay Lane-Pascoe in the television series Footballers' Wives that started broadcasting in 2002.
Chardonnay has been used as a given name in the African-American community in the United States since at least the 1990s.
