The small-amplitude classical cepheid HR 7308 has the shortest period known in our Galaxy for a classical cepheid. 1966-1969 photoelectric observations together with more recent data show a period of 1d.49078 with sinusoidal light variations. Except for the presence of the beat period, no secondary period can be found in the extensive 1966 data. The lack of a secondary period near Pi/Po = 0.7 sets HR 7308 apart from many other short-period classical cepheids.
