A quarry is a place from which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate has been excavated from the ground. A quarry is the same thing as an open-pit mine from which minerals are extracted. The only trivial difference between the two is that open-pit mines that produce building materials and dimension stone are commonly referred to as quarries.

The word quarry can also include the underground quarrying for stone, such as Bath stone.
