Woods‐Saxon potentials are utilized to predict the ground‐state binding energies of all A = 2 − 6 Λ hypernuclei. In total, twenty hypernuclei are considered in this paper. The model is generally within 500 keV of the measured ground‐state binding energy value in the                         ³H, ⁴H, ⁴He, ⁵He and ⁶He systems. The best fit to the known A ≤ 6 Λ hypernuclei ground‐state binding energies requires a potential form similar to the Rost interaction with the addition of a term dependent on the number of baryons in the system. The derived potentials are not unique and additional data are needed to further refine the Λ‐nucleus potential in light hypernuclei.
