Hidden variables may refer to:
- Hidden variable theories, in physics, the proposition that statistical models of physical systems (such as Quantum Mechanics) are inherently incomplete, and that the apparent randomness of a system depends not on collapsing wave functions, but rather due to unseen or unmeasurable (and thus "hidden") variables. In sharp contrast to the generally accepted Copenhagen Interpretation.
- Latent variables, in statistics, variables that are inferred from other observed variables
- Hidden transformation, in computer science, a way to transform a generic constraint satisfaction problem into a binary one by introducing new hidden variables
- Confounding or hidden variables in general. That is, a variable that actually creates the illusion of a causal relation (e.g. firemen often appear after smoke, not because smoke causes firemen, but because fire causes both smoke and firemen)

Famous quotes containing the words variable and/or hidden:
“There is not so variable a thing in nature as a lady’s head-dress.”
—Joseph Addison (1672–1719)
“Impenetrable in their dissimulation, cruel in their vengeance, tenacious in their purposes, unscrupulous as to their methods, animated by profound and hidden hatred for the tyranny of man—it is as though there exists among them an ever-present conspiracy toward domination, a sort of alliance like that subsisting among the priests of every country.”
—Denis Diderot (1713–1784)
