Accurate hyperfine-structure parameters for the ground and first excited states of lithium are reported. Hyperfine parameters are calculated from multiconfiguration Hartree-Fock (MCHF) wave functions using a recently written hyperfine-structure program, being a part of the MCHF Atomic Structure Package. Convergence of the hyperfine-strucure parameters is studied as the active set of orbitals is increased. The relativistic, finite-nuclear-size, and finite-nuclear-mass-corrected values of the magnetic hyperfine-structure constants of the 2{ital s} {sup 2}{ital S}{sub 1/2} and 2{ital p} {sup 2}{ital P}{sub 1/2,3/2} states of {sup 7}Li were determiend to be {ital A}{sub 1/2}=401.70 MHz and {ital A}{sub 1/2}=45.94 MHz, {ital A}{sub 3/2}=3.098 MHz, respectively. The final values are compared with experiments and with the most reliable theoretical values obtained with other methods.
