A UBV photometric investigation of the southern globular cluster NGC 2298 was carried out at the Cerro Tololo Inter-American Observatory using the 1.5 m reflector for the photoelectric and the photographic work. Fourteen stars were observed photoelectrically to apparent magnitude V = 16.22. With this sequence, 60 stars were calibrated photographically. The apparent distance modulus is (m- M) app = 15.70. The reddening is E (B-V) = 0.08. The true distance modulus is (m-M)/sub o/ = 15.46. The distance is 12.36 kpc from the Sun, 3.54 kpc from the galactic plane, and 18.72 kpc from the galactic center. The giant branch rises 3 magnitudes above the horizontal branch at (B -- V)/sub o/ = 1.4, characteristic of a metal poor object. (auth)
