  Shapes of light normal nuclei and $\Lambda$-hypernuclei are investigated
using relativistic mean field approach. The FSUGold parametrization is used for
this purpose. The addition of a $\Lambda$ is found to change the shape of the
energy surface towards prolate. The deformation in a $\Lambda$-hypernucleus,
when the hyperon is in the first excited state, is also discussed. The effect
of the inclusion of the hyperon on the nuclear radius is generally small with
one exception.
