A review of the lifetimes of B hadrons measured by the CDF
collaboration at Fermilab is presented.  The data correspond to 110 pb^-1 of
ppbar collisions at sqrt s = 1.8 TeV.  The inclusive B hadron lifetime is
measured using a high statistics sample of B -> J/psi X decays.  Species
specific lifetimes of the B^+, B^0, B^0_s, and Lambda^0_b are determined using
both fully reconstructed decays and partially reconstructed decays consisting
of a lepton associated with a charm hadron.
