This paper summarizes recent results on non-SUSY searches at the Fermilab Tevatron ppbar collider. All the analysis are based on the complete data samples recorded by both the CDF and D0 collaborations during the 1992-1995 running period (Run I), and correspond to ~ 100 pb^-1. Searches for new neutral heavy vector bosons, leptoquarks, dijet mass resonances, and associated production of new heavy scalars together with vector bosons show no evidence for new physics. Consequently, the results have been interpreted in terms of 95% confidence level limits on production cross sections and new particle masses.
