The distribution of angular correlations between prompt charm hadrons and primary charged particles in pp collisions is sensitive to the charm-quark hadronisation process. In this letter, charm-baryon correlations are measured for the first time by studying the azimuthal-angle difference between charged particles and prompt Λc+ baryons produced in pp collisions at a centre-of-mass energy of s=13 TeV, with the ALICE detector. Λc+ baryons are reconstructed at midrapidity (|y|<0.5) in the transverse-momentum interval 3
