We have succeeded in growing a high-quality single crystal of a non-4$$f$$ reference compound YCu$$_2$$Si$$_2$$ for a heavy-fermion superconductor CeCu$$_2$$Si$$_2$$, and observed the de Haas-van Alphen (dHvA) oscillation. The detected dHvA branches in YCu$$_2$$Si$$_2$$ indicate that the Fermi surfaces are multiply connected, and the dHvA frequencies are in the range from 9$$times10^6$$ to 2$$times10^8$$ Oe. These dHvA branches are found to be well explained by the results of energy band calculations. The corresponding cyclotron masses are light, ranging from 0.4 to 1.5 $$m_0$$, and are consistent with the electronic specific heat coefficient of 2.2 mJ/K$$^2cdot$$mol.
