Epitaxial La 1− x Sr x CrO 3 deposited on SrTiO 3 (001) is shown to be a p‐type transparent conducting oxide with competitive figures of merit and a cubic perovskite structure, facilitating integration into oxide electronics. Holes in the Cr 3d t 2g bands play a critical role in enhancing p‐type conductivity, while transparency to visible light is maintained because low‐lying d–d transitions arising from hole doping are dipole forbidden.
