Abstract Photometry is presented for nine new variables within the tidal radius of NGC 6652 and for 15 new variables outside the tidal radius. Of the former, four have periods indicating that they are probable RR Lyrae stars. Of the variables outside the tidal radius, eight have periods characteristic of such stars. It is unlikely that any of the RR Lyrae stars are actual members of NGC 6652; thus, this cluster probably possesses the red horizontal branch usually characteristic of its moderately high metallicity.
