Tevatron Experiments: CDF and D0 collected during October 1992 and February 1996 (Run I) a data sample of roughly 120 pb-1 p anti-p collisions at a center of mass energy s**(1/2) = 1.8 TeV. A large variety of physical studies have been performed using these data. Current paper reviews last results obtained searching for physics beyond the Standard Model. Direct Supersymmetry (SUSY) searches are not part of this review.
