Peppermint Grove is a western suburb of Perth, Western Australia on the north bank of the Swan River at Freshwater Bay. Its local government area, the smallest in the country, is the Shire of Peppermint Grove. The suburb was named after the Swan River peppermint trees (Agonis flexuosa) lining many streets. The suburb has long been associated with Western Australia's wealthiest and oldest families. Their prosperity is reflected in the many historical houses in the area, such as The Cliffe and the Federation Queen Anne style St Just. Colin Barnett, a former Premier of Western Australia, dubbed the suburb "Monaco of WA" due to its small size and concentration of wealth. It is also known as millionaire’s row and had the highest income of any suburb in Australia in 2022.
