We present long-slit spectra of three irregular galaxies from which we determine the stellar kinematics in two of the galaxies (NGC 1156 and NGC 4449) and ionized-gas kinematics in all three (including NGC 2366). We compare the stellar and ionized gas kinematics to the morphology of the galaxies and their HI kinematics. We find surprising differences between the kinematics of the stars, ionized gas, and neutral gas in these systems.
