UIrGe crystallizes in the orthorhombic TiNiSi structure and exhibits a huge magnetic anisotropy with the hard magnetization axis along the a-axis. Previous magnetic, transport and thermal studies indicated anti-ferromagnetic ordering below 15.8 K with an additional transition at 14.1 K [1]. For the present work, we have performed magnetization, magnetoresistance and specific heat measurements in magnetic fields up to 18 T. The data were taken in order to determine the magnetic phase diagrams for UIrGe in fields applied along the principle axes. [1] K. Prokes et al., Phys Rev B. 60 (1999) 9532
