A measurement of the helicity amplitudes and the parity violating decay asymmetry parameter, $\alpha_b$ for the $\Lambda_b^0$ hyperon decay $\Lambda_b^0\to J/\psi\Lambda^0$ is reported. The analysis is based on about 1400 $\Lambda_b^0$ and $\bar{\Lambda}_b^0$ baryons selected in 4.6 fb$^{-1}$ of proton-proton collision data recorded by the ATLAS experiment at the LHC with a center-of-mass energy of 7 TeV. By combining the $\Lambda_b^0$ and $\bar{\Lambda}_b^0$ samples under the assumption of CP conservation, the value of $\alpha_b$ was measured to be $0.28\pm0.16 ({\rm stat})\pm 0.06 ({\rm syst})$
