The cross section for elastic electron-deuteron scattering was measured in Jefferson Lab experiment 91-026. The deuteron elastic structure functions A(Q²) and B(Q²) have been extracted from this data. The final results for the ``electric'' structure function, A(Q<sup>2</sup>), in the range of 0.7 Ł Q<sup>2</sup> Ł 6.0 (GeV/c)<sup>2</sup> are presented. Preliminary results for the ``magnetic'' structure function, B(Q²), are presented in the range of 0.7 Ł Q² Ł 1.35 (GeV/c)². These data are compared to the theoretical predictions of both meson-nucleon and quark-gluon based models.
