The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at s=7TeV$${\sqrt{s}}=7~\mathrm {TeV}$$ and p–Pb collisions at sNN=5.02TeV$${\sqrt{{{s}}_{\scriptscriptstyle {\mathrm{NN}}}}}=5.02~\mathrm {TeV}$$ at the Large Hadron Collider. D0$$\mathrm{D}^{0}$$, D+$${\mathrm{D}^{+}}$$, and D∗+$${\mathrm{D}^{*+}}$$ mesons and their charge conjugates with transverse momentum 30.3GeV/c$${p}_{\mathrm{T}}>0.3~\mathrm {GeV}/c$$. The yield of charged particles in the correlation peak induced by the jet containing the D meson and the peak width are compatible within uncertainties in the two collision systems. The data are described within uncertainties by Monte-Carlo simulations based on PYTHIA, POWHEG, and EPOS 3 event generators.
