Tle effects of hydrostatic pressure on the InP:Yb luminescence were explored using a gasketed diamond anvil cell (DAC). The pressure dependence of the Yb^{3+} luminescence shows a small positive shift (0.96 meV/GPa) at low pressures (< 4 GPa) and a negative one (-0.04 meV/GPa) above 4 GPa. The spectra of the Yb^{3+} emission differ markedly in these two pressure ranges. It was concluded that intra-4f-shell transitions of the Yb^{3+} on indium substitutional (Td) site dominate in the spectrum above 4 GPa, whereas at lower pressures the emission has a different nature.
