We have used WFPC2 VRI observations to calculate the distances to three nearby galaxies, NGC 4214, UGC 685, and UGC 5456, using the tip of the red giant branch method. Our values for NGC 4214 (2.94 ± 0.18 Mpc) and UGC 685 (4.79 ± 0.30 Mpc) are the most precise measurements of the distances to these objects ever made. For UGC 5456 the data do not allow us to reach a decisive conclusion since there are two possible solutions, one leading toward a short distance around 3.8 Mpc and another one toward a long distance of 5.6 Mpc or more.
