The Mundaring and Hills Historical Society (MHHS) is a local history society for the Mundaring Shire based in Mundaring, Western Australia.
Affiliated with the Royal Western Australian Historical Society, the Society is a vital conduit for the disparate heritage and history issues in the Shire area. In earlier times a group of scattered communities linked by the railway branches that now constitutes the Railway Reserve Heritage
The Mundaring and Hills Historical Society was formed in 1989. Prior to this historical and heritage issues in the hills region saw significant losses of information, and loss of details of people and properties. The Society has corrected this, being able to attract significant funding and patronage to maintain a museum and to collect a wide range of materials and information. It is also one of the organisations heavily involved in the annual Trek the Trail which utilises sections of the Railway Reserve Heritage Trail as an outdoor event.
Mundaring and Hills Historical Society was a finalist in the 2011 West Australian Heritage Awards.
