A breast-shaped hill is a hill in the shape of a breast. Some such hills are named "Pap", an archaic word for the breast or nipple of a woman. Such anthropomorphic geographic features are found in different places of the world and in some cultures they were revered as the attributes of the Mother Goddess, such as the Paps of Anu, named after Anu, an important female deity of pre-Christian Ireland.

A hill is a landform that extends above the surrounding terrain. It often has a distinct summit, and is usually applied to peaks which are above elevation compared to the relative landmass, though not as prominent as mountains.
