We present differential CCD photometry for the high-amplitude delta Scuti star V567 Ophiuchi obtained in the Johnson V-band. It was observed on 15 nights in two consecutive years in order to resolve the long-standing ambiguity related to its secondary period. A frequency analysis of almost 5000 individual single-filtered measurements resulted in two independent frequencies (f1=6.6879c/d and f2=11.8266c/d) with a ratio of f1/f2=0.565. The presented photometric data are differential magnitudes relative to the comparison star C1 (GSC 00417-01714) from Powell et al. (1990PASP..102.1131P) (1 data file).
