We report $\Lambda^{\ast}$(1520) production in pp collisions at $\sqrt{s}$ = 7 TeV and in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV by ALICE at the LHC. The study of $\Lambda^{\ast}$ production is important because its lifetime is comparable to the lifetime of the fireball and it contains all three light quarks (uds) as valence quarks. The study of $\Lambda^{\ast}$ production can also be used to investigate the medium between chemical and thermal freezeout, since its decay products may interact with the hadronic medium. In this poster presentation we will show mass, width and transverse momentum spectra both in pp and p-Pb systems. The ratio of $\Lambda^{\ast}$ over $\Lambda$(1115) is expected to be the same in p-Pb as in pp collisions; it will be compared to that measured at RHIC energies and to the prediction from the thermal model in Pb-Pb collisions.
