The magnetic properties and magnetocaloric effect (MCE) in DyNi₄Si have been studied by the magnetization and specific heat measurements. The saturation magnetic moment in μ₀H = 9 T is equal to 7.9 μ_B/f.u at 4.2 K. A significant MCE has been observed around the second order phase transition at T_C = 11 K. The maximum magnetic entropy change is -ΔS_M = 14.5 J kg^-1K^-1 for the magnetic field change of 9 T.
