The high collision energies reached at the LHC lead to significant production yields of light (anti-) and hyper-nuclei in proton-proton, proton-lead and, in particular, lead-lead collisions. The excellent particle identification capabilities of the ALICE apparatus, based on the specific energy loss in the Time Projection Chamber and the velocity information obtained with the Time-Of-Flight detector, allow for the detection of these rarely produced particles. Furthermore, the Inner Tracking System gives the possibility to separate primary nuclei from those originating from the decay of hyper-nuclei. One example is the hypertriton which is reconstructed in the decay channel 3LambdaH -> 3H + pi. We present results on the production of stable nuclei and anti-nuclei in Pb--Pb and lighter collision systems. Hypernuclei production rates in Pb--Pb will also be shown. All results are compared with predictions for the production in thermal (statistical) models and alternatives which are based on coalescence mechanisms. The results obtained provide a solid basis for searches for lighter exotica such as the H-Dibaryon. .
