  We report the experimental study on the structural and magnetic properties of
a new ternary intermetallic compound $\mathrm{Sm_2AgSi_3}$. The properties of
the sample were investigated in detail by X-ray diffraction, dc-magnetization,
and heat capacity measurements. The polycrystalline compound of
$\mathrm{Sm_2AgSi_3}$ crystallizes in the $\mathrm{ThSi_2}$-type tetragonal
structure (space group ${I_{4_1}/amd}$). The temperature-dependent
dc-magnetization and heat capacity results demonstrate that the compound
undergoes ferromagnetic behaviour with a Curie temperature ($T_C$) of 14 K. The
large coercive field in hysteresis loops and the thermomagnetic irreversibility
in the ferromagnetic region revealed that the compound exhibits a large
magnetic anisotropy. The magnitude of the applied field and the coercivity
obtained from the M-H loops corroborate with the thermomagnetic irreversibility
in the magnetization data. The magnetic contribution of the heat capacity
reveals a broad Schottky-type anomaly above $T_C$, due to the presence of the
crystal electric field effect of $\mathrm{Sm^{3+}}$ in $\mathrm{Sm_2AgSi_3}$.
