We present CCD imaging and photometry in B and Cousins R of the dwarf irregular galaxies UGC 4459 (=DDO 53), UGC 5272 (A=DDO 64 and B), UGC 5340 (=DDO 68), UGC 6456, UGC 7559 (=DDO 126), UGC 8024 (=NGC 4789A=DDO 154), UGC 8091 (= GR 8=DDO 155), UGC 8320 (=DDO 168), UGC 8760 (=DDO 183), and DDO 210. For DDO 210 we also give results in the V filter. Photometry of the resolved stars was carried out on background-subtracted images using DAOPHOT. The tables of measurements include positions, magnitudes, colors, a magnitude error, and a color error. Integrated fluxes and colors are also reported. The single-star photometry is compared to previous results in three of the galaxies (UGC 8024, UGC 8091, DDO 210).
