Measurements of the $B_u$, $B_d$, and $B_s$ meson lifetime using semileptonic $B_u \rightarrow e \nu D^0 X, B_d \rightarrow e \nu D^* X, B_s \rightarrow l \nu D_s X$ events and exclusive $B_u \rightarrow \psi^{(\prime)} K^{(*)}, B_d \rightarrow \psi^{(\prime)} K^{(*)}_{(s)}, B_s \rightarrow \psi \phi$ 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$^{-1}$ sample of 1.8 TeV $\overline{p}p$ collisions collected in 1992-93 at the Fermilab Tevatron collider. Comparisons with previous measurements will be shown.
