Abstract : We present a selection of beyond-the-standard-model searches of heavy resonances from the CDF and D0 experiments at the Tevatron collider. The data used are part or all of the Run IIa Tevatron data giving more than 1 fb1 per experiment. The searches have been performed for 0, spin ½ , spin 1 and spin 2 resonances.All the searches and the limits on the different cross section times branching fractions are model independent. They have been interpreted using different models, such as : spin 0 third-generation neutrino, spin ½ exited quark, spin 1 w-and Z- and also spin 2 Randall-sundrum graviton. No evidence of new physics or deviations from the standard model were observed. Limits on particle masses are thus extracted.
