We present Hubble Space Telescope ACS images and color-magnitude diagrams for 24 nearby galaxies in and near the constellation of Centaurus with radial velocities V_LG_<550km/s. Distances are determined based on the luminosities of stars at the tip of the red giant branch that range from 3.0 to 6.5Mpc. The galaxies are concentrated in two spatially separated groups around Cen A (NGC 5128) and M83 (NGC 5236).
