We prescribe a pseudo-Newtonian vector potential for studying accretion disksaround Kerr black holes. The potential is useful to study the inner propertiesof disk not confined to the equatorial plane where general relativistic effectis indispensable. Therefore, we incorporate the essential properties of themetric at the inner radii through the pseudo-Newtonian potential derived fromthe general Kerr spacetime. The potential, reproducing most of the salientfeatures of the general-relativity, is valid for entire regime of Kerrparameter. It reproduces the last stable circular orbit exactly as that in theKerr geometry. It also reproduces last bound orbit and energy at last stablecircular orbit with a maximum error ~7% and ~15% respectively upto an orbitalinclination 30 degree.
