Studies of the production of light- and heavy-flavour baryons are of prominent importance to characterise the partonic phase created in ultrarelativistic heavy ion collisions and to investigate hadronisation mechanisms at the LHC. Studies performed in p--Pb and pp collisions have revealed unexpected features, qualitatively similar to what is observed in larger collision systems and, in the charm sector, not in line with the expectations from $e^{+}e^{-}$ and $e^{-}$p interactions. The ALICE experiment has exploited its excellent tracking and PID capabilities down to low transverse momentum to perform an extensive study of protons, hyperons and charmed baryons. A critical discussion of the most recent results on light (protons and hyperons) and heavy-flavour ($\Lambda_{\mathrm{c}}$ and $\Xi_{\mathrm{c}}$) baryon production will be presented, together with a comparison to phenomenological models. Emphasis will be given to the discussion of the impact of these studies on our understanding of hadronisation processes.
