Purity is the absence of impurity or contaminants in a substance. This term also applies to the absence of vice in human character.
- Ritual purification, a feature of many religions
- Purity in Buddhism, a spiritual purity of character or essence
- Purity (quantum mechanics), a measure of correlation between a system and its environment
- Purity (gas), an indication of the amount of other gases in a particular gas

Purity may also refer to:
Purity is a 1916 American silent drama film, directed by Rae Berger and starring Audrey Munson. The film's scenario was written by Clifford Howard and is notable for its nude scenes, which caused it to be banned and preached against in some towns.
Purity was long presumed to be lost. However, in 2004, a copy was rediscovered in France. A copy of the film is now preserved at the Centre national de la cinématographie in Paris.
The purity of gas is an indication of the amount of other gases it contains. A high purity refers to a low amount of other gases. Gases of higher purity are considered to be of better quality and are usually more expensive.
The purity of gas can be expressed as a percentage value or as a decimal fraction. The decimal fraction is an abbreviation of the percentage value, where the first digit represents the number of nines in the percentage value and the last digit represents the last digit of the percentage value. For example, a purity of 99.97% can be abbreviated as purity 3.7 and a purity of 99.99990% is the same as purity 6.0.

In quantum mechanics, and especially quantum information theory, the purity of a quantum state is a scalar defined as
γ ≡ Tr(ρ)
where ρ is the density matrix of the state. The purity can range between unity, corresponding to a completely pure state, and 1/d , corresponding to a completely mixed state. (Here, d is the dimension of the density matrix.)
Purity is trivially related to the Linear entropy S of a state by
γ = 1 − S .
In the mathematical field of algebraic geometry, purity is a theme covering a number of results and conjectures, which collectively address the question of proving that "when something happens, it happens in a particular codimension".
For example, ramification is a phenomenon of codimension 1 (in the geometry of complex manifolds, reflecting as for Riemann surfaces that ramify at single points that it happens in real codimension two). A classical result, Zariski–Nagata purity of Masayoshi Nagata and Oscar Zariski, called also purity of the branch locus, proves that on a non-singular algebraic variety a branch locus, namely the set of points at which a morphism ramifies, must be made up purely of codimension 1 subvarieties (a Weil divisor). There have been numerous extensions of this result into theorems of commutative algebra and scheme theory, establishing purity of the branch locus in the sense of description of the restrictions on the possible "open subsets of failure" to be an étale morphism.
There is also a homological notion of purity that is related, namely a collection of results stating that cohomology groups from a particular theory are trivial with the possible exception of one index i. Such results were established in étale cohomology by Michael Artin (included in SGA 4), and were foundational in setting up the theory to contain expected analogues of results from singular cohomology. A general statement of Alexander Grothendieck known as the absolute cohomological purity conjecture was proved by Ofer Gabber. It concerns a closed immersion of schemes (regular, noetherian) that is purely of codimension d, and the relative local cohomology in the étale theory. With coefficients mod n where n is invertible, the cohomology should occur only with index 2d (and take on a predicted value).
Purity is a novel by American author Jonathan Franzen. It was published on September 1, 2015 by Farrar, Straus and Giroux.
