We define a class of quadratic differential algebras which are generated asdifferential graded algebras by the elements of an Euclidean space. Such adifferential algebra is a differential calculus over the quadratic algebra ofits elements of differential degree zero. This generalizes for arbitraryquadratic algebras the differential graded algebra of exterior polynomialdifferential forms for the algebra of polynomial functions on $\mathbb R^n$. Weinvestigate the structure of these differential algebras and their connectionwith the Koszul complexes of quadratic algebras.
