We study the signals for supersymmetry at the Fermilab Tevatron and its proposed energy upgrade (called the DiTevatron here) ([radical][ital s] =4 TeV) in various well-motivated supersymmetric models. We consider the trilepton signature in the decay of pair-produced charginos and neutralinos, the missing energy signature in gluino and squark production, and the [ital b[bar b]] signal in the decay of the lightest supersymmetric Higgs boson produced in association with a [ital W] or [ital Z] boson. In each case we perform signal and background studies, using Monte Carlo and/or real data to estimate the sensitivity to these signals at the Tevatron and DiTevatron with the Main Injector, for short- and long-term integrated luminosities of [ital scrL]=10 and 25 fb[sup [minus]1], and 5[sigma] statistical significance. We conclude that one could probe chargino masses as high as [ital m][sub [chi]1][sup [plus minus]][similar to]180 (200) GeV, gluino masses as high as [ital m][sub [ital [tilde g]]][similar to]450 (750) GeV, and lightest Higgs boson masses as high as [ital m][sub [ital h]][similar to]110 (120) GeV at the Tevatron (DiTevatron). A high-luminosity option at the Tevatron (10[sup 33] cm[sup [minus]2] s[sup [minus]1]) may compensate somewhat for the higher reach of the DiTevatron, but only in the trilepton and Higgs signals. However, these gains may be severely compromised once the multiple-interaction environment of the high-luminosity Tevatron is accounted for.
