Ralahyne, Heritage villa in Clayfield, Queensland, Australia.

Ralahyne is a single-story timber villa in Clayfield, Queensland, Australia. The house features a hipped roof, cast-iron balustrading, verandahs on the eastern and northern sides, a long servants' wing to the south, and a ballroom with a domed ceiling and skylights.

Built in 1888 for Robert Gray, the Under Colonial Secretary, Ralahyne was designed by architect George HM Addison to replace an earlier four-room house. The property gained recognition on the Queensland Heritage Register for its architectural value from that period.

The house's names trace its owners: East View until 1892, Koojarewon until 1900, Huntington, then Nowranie from 1907, and Ralahyne from 1920 under Henrietta Watson, whose family kept it until 1985. Robert Gray, the first owner, became Commissioner of Railways in 1889. The 1904 Hall & Dods additions, worth over £1000, gave the house its enclosed rear verandah ballroom.

The property is accessible by public transport and located in a residential area of Clayfield. Visitors should check in advance whether access is possible, as this is a private residence.

The property underwent multiple name changes over the decades, starting as East View, then Koojarewon, followed by Huntington, before becoming Ralahyne in 1920. Each name shift reflected the different families who lived there and their evolving connection to the place.
