The pressure dependence of the elastic constants C{sub ij} of GaP have been measured up to 15 GPa in a diamond anvil cell. Brillouin backscattering experiments along the principal crystallographic directions yielded four combinations of elastic constants from which the three independent C{sub ij} were extracted. Above 15 GPa the closure of the energy band gap prevents the detection of the signal. {copyright} {ital 1999} {ital The American Physical Society}
