  This paper reviews the most recent results on searches for physics beyond the
Standard Model at Tevatron. Both the collider experiments: CDF and DO are
performing a large variety of searches such as searches for scalar top and
scalar bottom particles, search for new gauge bosons, search for long-lived
massive particles and general searches for new particles decaying into dijets.
The results, summarized here, are a selection of what obtained recently by both
the collaborations using the Run II data, collected so far.
