We first discuss the deformation properties of $\\Lambda$ hypernuclei in the $sd$-shell region. Based on the relativistic mean-field (RMF) approach, we show that the oblate deformation for $^{28}$Si nucleus may disappear when a $\\Lambda$ particle is added to this nucleus. We then discuss the rotational excitations of $^{25}_{\\Lambda}$Mg nucleus using the three-dimensional potential energy surface in the deformation plane obtained with the Skyrme-Hartree-Fock method.
