Hlane Royal National Park is a park in Swaziland, roughly 67km northeast of Manzini along the MR3 road. Prior to the park being public, it was a private royal hunting ground. Hlane, meaning 'wilderness', was named by King Sobhuza II. It is now held in trust for the Nation by His Majesty King Mswati III,  and is managed by Big Game Parks, a privately owned body.
It is Swaziland's largest protected area and also the largest park. The park and its adjacent dispersal areas covers 30,000 hectares of Swazi bushveld. It is a flat lowland area, covered with ancient hardwood trees like knobthorn, leadwood and tambuti, with some grasslands and shallow pans.
A network of game-viewing roads criss-cross the park’s flat terrain. Accommodation is available in thatched huts and cottages.
The park was bisected by the MR3 highway in the 1960s under pressure from sugar estates at the park's borders. They claimed that the highway would cause no environmental damage, but now hundreds of antelope, wild boar, buffalo and other game are struck by vehicles each year.
