Chilliwack was a Canadian rock band that existed during the 1970s and 1980s. They are perhaps best remembered for their three biggest songs "My Girl (Gone Gone Gone)", "I Believe" and "Whatcha Gonna Do." Even though those three hits were their only popular singles in the USA, the band has achieved legendary status in its native Canada.

Chilliwack was a provincial electoral district in the Canadian province of British Columbia from 1916. It was the successor riding to the Chilliwhack riding, which used the older spelling of the name and had slightly different boundaries. Chilliwhack was the successor riding to Westminster-Chilliwhack, which was one of four subdivisions of the old rural Westminster riding, the others being the ridings that became, after similar name-changes, Delta, Dewdney and Richmond (electoral district), which are the parent ridings of all current Fraser Valley electoral districts.
