'''Constraint''' may refer to:
* [[Constraint (computer-aided design)]], a demarcation of geometrical characteristics between two or more entities or solid modeling bodies
* [[Constraint (mathematics)]], a condition of an optimization problem that the solution must satisfy
* [[Constraint (mechanics)]], a relation between coordinates and momenta
* [[Constraint (computational chemistry)]]
* [[Constraint (information theory)]], the degree of statistical dependence between or among variables
* [[Constraints (journal)|''Constraints'' (journal)]], a scientific journal
