In situ high-pressure angle dispersive synchrotron X-ray diffraction studies of molybdenum diselenide (MoSe2) were carried out in a diamond-anvil cell to 35.9 GPa. No evidence of a phase transformation was observed in the pressure range. By fitting the pressure-volume data to the third-order Birch-Murnaghan equation of state, the bulk modulus, K0T, was determined to be 45.7{+-}0.3 GPa with its pressure derivative, K'0T, being 11.6{+-}0.1. It was found that the c-axis decreased linearly with pressure at a slope of -0.1593 when pressures were lower than 10 GPa. It showed different linear decrease with the slope of a -0.0236 at pressures higher than 10 GPa.
