The results of spectroscopic and photometric observations of the F4 star HD 123058 are reported. The spectroscopic measurements were carried out at the ESO La silla coude spectrograph of the 1.52-m telescope, covering the blue spectral range from 3500-5000 A. The broadband UBV photometric observations were made with an EMI 9502 SA photomultiplier mounted on the 61-cm telescope. Broad absorption lines were found in the spectrum of HD 123058 which are attributed to a high rotation rate of about 61 km/s. When combined with published data, the photometric data are consistent with a spectral classification of the star. In comparison with a model atmosphere grid the photometric data yield an effective temperature of 6670 K. The Fe/H abundance ratio is 0.02 which indicates a probable age of less than 4 x 10 to the 9th yr, while the small value derived for the color difference suggests that the star lies near the zero-age main sequence. The distance of HD 123058 is estimated to be 70 (+ or -8) pc. It is shown on the basis of the observational results that HD 123058 is not a spectroscopic binary.
