This paper reviews the most recent results on searches for
physics beyond the Standard Model at Tevatron. Both the collider
experiments: CDF and D0 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.
