Title: Heavy Flavor Production at the Tevatron Abstract: 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, measurements are made of the B hadron relative fragmentation fractions, and production cross sections of the B^+ and upsilon. An upper limit for the production cross-section times decay branching fraction for eta_b to J/psi J/psi is also reported.
