We present a measurement of azimuthal correlations between inclusive J/$\psi$and charged hadrons in p-Pb collisions recorded with the ALICE detector at theCERN LHC. The J/$\psi$ are reconstructed at forward (p-going, 2.03 $<$ y $<$3.53) and backward (Pb-going, $-$4.46 $<$ y $<$ $-$2.96) rapidity via their$\mu^+\mu^-$ decay channel, while the charged hadrons are reconstructed atmid-rapidity ($|\eta|$ $<$ 1.8). The correlations are expressed in terms ofassociated charged-hadron yields per J/$\psi$ trigger. A rapidity gap of atleast 1.5 units is required between the trigger J/$\psi$ and the associatedcharged hadrons. Possible correlations due to collective effects are assessedby subtracting the associated per-trigger yields in the low-multiplicitycollisions from those in the high-multiplicity collisions. After thesubtraction, we observe a strong indication of remaining symmetric structuresat $\Delta\varphi$ $\approx$ 0 and $\Delta\varphi$ $\approx$ $\pi$, similar tothose previously found in two-particle correlations at middle and forwardrapidity. The corresponding second-order Fourier coefficient ($v_2$) in thetransverse momentum interval between 3 and 6 GeV/$c$ is found to be positivewith a significance of about 5$\sigma$. The obtained results are similar to theJ/$\psi$ $v_2$ coefficients measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$= 5.02 TeV, suggesting a common mechanism at the origin of the J/$\psi$ $v_2$.
