A hill is a landform that extends above the surrounding terrain. Hills often have a distinct summit, although in areas with scarp/dip topography a hill may refer to a particular section of flat terrain without a massive summit (e.g. Box Hill, Surrey).

The distinction between a hill and a mountain is unclear and largely subjective, but a hill is generally somewhat lower and less steep than a mountain. In the United Kingdom geographers historically regarded mountains as hills greater than 1,000 feet (300 m) above sea level, which formed the basis of the plot of the 1995 film The Englishman Who Went Up a Hill But Came Down a Mountain. In contrast, hillwalkers have tended to regard mountains as peaks 2,000 feet (610 m) above sea level: the Oxford English Dictionary also suggests a limit of 2,000 feet (610 m). This has led to Cavanal Hill in Poteau, Oklahoma, receive billing as the "World's Tallest Hill" due to its height of 1,999 feet (609 m). Mountains in Scotland are frequently referred to as "hills" no matter what their height, as reflected in names such as the Cuillin Hills and the Torridon Hills. In Wales, the distinction is more a term of land use and appearance and has nothing to do with height.

The Black Hills (Pahá Sápa in Lakota, Moʼȯhta-voʼhonáaeva in Cheyenne) are a small, isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, USA.Harney Peak, which rises to 7,244 feet (2,208 m), is the range's highest summit. The Black Hills encompass the Black Hills National Forest and are home to the tallest peaks of continental North America east of the Rockies. The name "Black Hills" is a translation of the Lakota Pahá Sápa. The hills were so-called because of their dark appearance from a distance, as they were covered in trees.

Native Americans have a long history in the Black Hills. After conquering the Cheyenne in 1776, the Lakota took over the territory of the Black Hills, which became central to their culture. In 1868, the U.S. government signed the Fort Laramie Treaty of 1868, exempting the Black Hills from all white settlement forever. However, when European Americans discovered gold there in 1874, as a result of George Armstrong Custer's Black Hills Expedition, erstwhile miners swept into the area in a gold rush. The US government re-assigned the Lakota, against their wishes, to other reservations in western South Dakota. Unlike most of South Dakota, the Black Hills were settled by European Americans primarily from population centers to the west and south of the region, as miners flocked there from earlier gold boom locations in Colorado and Montana.
