Abstract
We extend the quark mean field model to the study of \Lambda hypernuclei. Without adjusting parameters, the properties of \Lambda hypernuclei can be described reasonably well. The small spin-orbit splittings for \Lambda in hypernuclei are achieved, while the \Lambda single particle energies in the present model are slightly underestimated as compared with the experimental values. About 3% deviation from the quark model prediction for the \omega-\Lambda couplings is required in order to reproduce the experimental single particle energies.
