The term highland or uplands is used to denote any mountainous region or elevated mountainous plateau. Generally speaking, upland (or uplands) tends to refer to ranges of hills, typically up to 500–600 m. Highland (or highlands) is usually reserved for ranges of low mountains.
Probably the most known highlands in the anglosphere are the Scottish Highlands in the United Kingdom, the mountainous region north and west of the Highland Boundary Fault. The Highland council area is a local government area in the Scottish Highlands and Britain's largest local government area.
Many countries have areas that are officially or unofficially referred to as highlands. Other than Scotland, these include parts of Tibet,Ethiopia, Kenya, Eritrea, Yemen, Ghana, Nigeria, Papua New Guinea, Syria, Cantabria and Nova Scotia (the latter being Latin for 'New Scotland' due to its resemblance to the country).
Synonymous terms used in other countries include high country, used in New Zealand, New South Wales, Victoria, Tasmania and Southern Queensland in Australia, and parts of the United States (notably Western North Carolina), highveld, used in South Africa and Roof of the World, used for Tibet.
