We report on a fundamental thickness limit of the itinerant ferromagneticoxide SrRuO$_3$ that might arise from the orbital-selective quantum confinementeffects. Experimentally, SrRuO$_3$ films remain metallic even for a thicknessof 2 unit cells (uc), but the Curie temperature, T$_C$, starts to decrease at 4uc and becomes zero at 2 uc. Using the Stoner model, we attributed the T$_C$decrease to a decrease in the density of states (N$_o$). Namely, in the thinfilm geometry, the hybridized Ru-d$_yz,zx$ orbitals are terminated by top andbottom interfaces, resulting in quantum confinement and reduction of N$_o$.
