The name Chelsea may refer to one of several locations, notably in London and New York City, and some organisations associated with those places. It is also a moderately common given name, for which there are several alternative spellings, including Chelsee, Chelsey, Chelsi, Chelsie and Chelsy.
The name originally derives from the Old English for chalk wharf, applied descriptively to the neighbourhood of Chelsea in London. The successive fame of the name in different generations such as the Chelsea porcelain in the 18th century, Swinging Chelsea in the 1960s, and today's Chelsea Football Club help to explain the spread of the name.
