Single crystalline samples of the van der Waals antiferromagnet CrPS4 were studied by measurements of specific heat and comprehensive anisotropic temperature- and magnetic-field-dependent magnetization. In addition, measurements of the heat capacity and magnetization were performed under pressures of up to \ensuremath∼21 and \ensuremath∼14 kbar, respectively. At ambient pressure, two magnetic transitions are observed: second order from a paramagnetic to an antiferromagnetic state at TN\ensuremath∼37 K, and a first-order spin reorientation transition at T*\ensuremath∼34 K. Anisotropic H\text\ensuremath-T phase diagrams were constructed using the M(T,H) data. As pressure is increased, TN is weakly suppressed with dTN/dP\ensuremath≈\ensuremath-0.1 K/kbar. T*, on the other hand, is suppressed quite rapidly, with dT*/dP\ensuremath≈\ensuremath-2 K/kbar, extrapolating to a possible quantum phase transition at Pc\ensuremath∼15 kbar.
