Measurements of the B{sub u}, B{sub d}, and B{sub s} meson lifetime using semileptonic B{sub U} {yields} e{nu}D* X, B{sub s} {yields} l{nu}D{sub s}X events and exclusive B{sub u} {yields} {psi}({prime})K({sub s})(*)B{sub s} {yields} {psi}{phi} events are presented. These results used the precise position measurements of the CDF SVX silicon vertex detector and were obtained from a 19.3 pb{sup {minus}1} sample of 1.8 TeV {bar p}p collisions collected in 1992--93 at the Fermilab Tevatron collider. Comparisons with previous measurements will be shown.
