Thin films of the model charge-density-wave compound Rb 0.30 MoO 3 ͑blue bronze͒ have been grown using pulsed-laser deposition. Films are single-phase Rb 0.30 MoO 3 , and consist of grains with typical sizes on the order of micrometers. The charge-density-wave chains are parallel to the film plane. Heteroepitaxial growth of Rb 0.30 MoO 3 is found on SrTiO 3 ͑100͒ substrates. The blue-bronze grains align their chains with the two principal axes of the square surface lattice of SrTiO 3 ͑100͒. Preferential orientation into a single direction can be obtained on SrTiO 3 ͑510͒. Measurements of the film resistance as a function of temperature show a transition to the charge-density-wave state near 182 K.
