This paper is devoted to the study of mixed finite element approximations [as introduced by the first author, \textit{F. Brezzi}, \textit{J. Douglas}, \textit{M. Fortin} and \textit{L. D. Marini}, Mathematical Modelling and Numerical Analysis 21, 581-604 (1987; Zbl 0689.65065)] of a second-order elliptic equation with Dirichlet boundary conditions. Superconvergence of the method is shown.
