In this paper the pressure dependence of crystal field (CF) parameters and free-ion parameters of the Eu<SUP>3+</SUP> ion in Y<SUB>2</SUB>O<SUB>2</SUB>S:Eu is studied experimentally in the pressure range from 0 to 13 GPa. Pressure strengthens the interionic interaction in the crystal. The CF strength parameter S increases by a factor of 11%. The Slater parameter F<SUB>2</SUB> and the spin-orbit parameter show about 0. 4 % and 0. 2 % decrease, respectively.
