We present magnetic and transport properties of PrRh$_{ 2}$Si$_{ 2}$ single crystals which exhibit antiferromagnetic order below T$_{ N}$ = 68 K. Well defined anomalies due to magnetic phase transition are observed in magnetic susceptibility, resistivity, and specific heat data. The T$_{ N}$ of 68 K for PrRh$_{ 2}$Si$_{ 2}$ is much higher than 5.4 K expected on the basis of de-Gennes scaling. The magnetic susceptibility data reveal strong uniaxial anisotropy in this compound similar to that of PrCo$_{ 2}$Si$_{ 2}$. With increasing pressure T$_{ N}$ increases monotonically up to T$_N$ = 71.5 K at 22.5 kbar.
