Recent results on heavy flavor production from the CDF and D0 experiments at the Tevatron are reported, using up to 1 fb-1 of accumulated luminosity per experiment. The first observation of resonant Lambda0(b) pi+ states, consistent with the lowest-lying charged Sigma_b states, is announced. Measurements are made of the B hadron relative fragmentation fractions and production cross sections of the B+ and Upsilon(1S). An upper limit for the production cross section of eta_b --> J/Psi J/Psi is also set.
