(For other uses, see Kadena (disambiguation).) Kadina is a town located on the Yorke Peninsula of South Australia, approximately 144 kilometres north-northwest of the state capital of Adelaide. The largest town of the Peninsula, Kadina is one of the three Copper Triangle towns famous for their shared copper mining history. The three towns are known as "Little Cornwall" for the significant number of immigrants from Cornwall that worked at the mines in the late 19th century. The name "Kadina" is thought to be derived from Kadiyinya, an (indigenous) Narungga tribe word meaning 'Lizard Plain'.
