%X The inclusive production of the charm-strange baryon Ω<sub>c</sub><sup>0</sup> is measured for the first time via its hadronic decay into Ω<sup>−</sup>π<sup>+</sup> at midrapidity (| y  < 0.5| in proton-proton (pp) collisions at the centre-of-mass energy √s = 13  TeV with the ALICE detector at the LHC. The transverse momentum (P<sub>T</sub>) differential cross section multiplied by the branching ratio is presented in the interval 2  <  P<sub>T</sub>  <  12 GeV/c . The  P<sub>T</sub> dependence of the  Ω<sup>0</sup><sub>c</sub>-baryon production relative to the prompt D<sup>0</sup>-meson and to the prompt Ξ<sup>0</sup><sub>c</sub>-baryon production is compared to various models that take different hadronisation mechanisms into consideration. In the measured  interval, the ratio of the P<sub>T</sub>-integrated cross sections of Ω<sup>0</sup><sub>c</sub> and prompt ∆<sup>+</sup><sub>c</sub> baryons multiplied by the Ω<sup>+</sup>π<sup>−</sup> branching ratio is found to be larger by a factor of about 20 with a significance of about 4 σ when compared to  e<sup>+</sup>e<sup>−</sup> collisions.
