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(Q2), in the range of 0.7 Q2 6.0 (GeV/c)2 are presented. Preliminary results for the ``magnetic'' structure function, B(Q2), are presented in the range of 0.7 Q2 1.35 (GeV/c)2. These data are compared to the theoretical predictions of both meson-nucleon and quark-gluon based models.
