We present new BV CCD photometry, light curves, and ephemerides for 9 previously know and 28 newly detected RR Lyrae variables in the globular cluster M75. The photometry used for the detection of the additional variables was obtained with the image subtraction package ISIS. The data were acquired on an observing run in July 1999 and range over 7 observing nights. Estimates of fundamental photometric parameters are presented including intensity- and magnitude-averaged B and V magnitudes, magnitude-averaged colors, pulsation periods, and pulsation amplitudes.
