We report measurements of the in-plane resistivity ({rho}{sub {ital a}{ital b}}) and out-of-plane resistivity ({rho}{sub {ital c}}) on a Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} high-temperature superconducting single crystal under hydrostatic pressure up to 20 kbar. {rho}{sub {ital a}{ital b}} has an initial derivative {ital d}(ln{rho}{sub {ital a}{ital b}})/{ital dP} of {minus}0.75% kbar{sup {minus}1}, while {rho}{sub {ital c}} depends much more strongly on pressure, {ital d}(ln{rho}{sub {ital a}{ital b}})/{ital dP}{approx}{minus}4.0% kbar{sup {minus}1}. The superconducting transition temperature ({ital T}{sub {ital c}}) in both configurations increases monotonically by +0.15 K/kbar in the pressure range covered.
