Abstract: The azimuthal anisotropy of particles associated with jets (jet particles) at midrapidity is measured for the first time in p--Pb and Pb--Pb collisions at $\sqrt{s_{NN}}$ $=$ 5.02 TeV down to transverse momentum ($\it{p}_{\rm T}$) of 0.5 GeV/$c$ and 2 GeV/$c$, respectively, with ALICE. The second-order Fourier coefficient of the jet-particle azimuthal distribution ($v_2$) in high-multiplicity p--Pb collisions is positive, with a significance reaching 6.8$\sigma$ at low $\it{p}_{\rm T}$. Comparisons with the inclusive charged-particle $v_2$ and with AMPT calculations are discussed. The model describes qualitatively the main features of the jet-particle $v_2$ in high-multiplicity p--Pb collisions and indicates that the positive jet-particle $v_2$ is generated by parton interactions.
