We review recent measurements of heavy B hadron states including masses and lifetimes of the B-_c meson as well as excited B states (B**, B**_s). We discuss properties of the B0(s) meson such as lifetime, lifetime difference Delta Gamma_s/Gamma_s and CP violation in B0(s) --> J/psi phi decays. We also summarize new measurements of the masses and lifetimes of bottom baryons including the Lambda0(b) baryon, the Sigma_b baryon states as well as the Xi-_b and Omega-_b baryons.
