It was first recorded in 1217 by an Old English word meaning "Calf Island", from Cealf meaning calf. As the name implies, Chalvey lies low on the plain of the River Thames, and there may have been enough of a rise for an island to stand above the slough from which the later town takes its name.
At some point between 1850 and 1880, a local legend developed about the "Chalvey Stab Monkey" involving an organ grinder and a stabbed monkey; the first person to get blind drunk on the anniversary of the monkey's funeral is declared "Mayor of Chalvey". Traditionally, residents of Chalvey have been known as "stab-monks".:40 A long-standing local joke suggests that Chalvey's main industry is in the Treacle Mines. On occasion, this has been taken to be a reference to the local sewage works.
It was stated on the "Immigration - How We Lost Count" edition of the BBC1 documentary Panorama on 23 July 2007 that Chalvey is severely overcrowded, and that most of its residents are immigrants and members of ethnic minorities. Chalvey has a large Asian population.
The first recorded Lord of the Manor of Chalvey was recorded in the year 1502. The current Lord of Chalvey, Christopher Johnson, lives in the United States.
