In mathematics:

- Denseness: A set is dense in another set if the closure of the former set equals the latter set.
^{[e]} - Density function: Describes, in mathematics, a measure (including probability and statistical distributions) by means of its integrals over subsets.
^{[e]} - Density (number theory): The asymptotic frequency of a subset of the natural numbers.
^{[e]} - Packing density: Ratio of area (or volume) covered by non-overlapping bodies in a region to the area (or volume) of that region.
^{[e]} - Covering density: Ratio of the total area (or volume) of overlapping bodies covering a region to the area (or volume) of that region.
^{[e]} - Dense subset: In a topological space, a subset whose closure (i.e., all boundary points added) is the whole space.
