William Edward Everard (December 1819 – 25 August 1889) was a South Australian businessman and politician. Everard was the son of Dr. Charles George Everard (1794–1876) and his wife Catherine (1786–1866), originally of London. The family, which included his mother and brothers Charles John Everard (ca.1822 – 22 July 1892) and James George (died 3 May 1840, aged 15), arrived in Adelaide on the ship Africaine under Captain John Finlay Duff in 1836. His father was one of the first eighteen elected to South Australia's unicameral Legislative Council in 1839.
