Photometric data extracted from more than 5000 CCD observations of the Milky Way field star NSV 01450, with galactic co-ordinates l =145^°.9 and b=4^° .9, show that this object is a bright classical Cepheid with a period of 12.639 +/- 0.020 days and an average < V > magnitude of 11.045+/- 0.016. The computed colour excess is E(B-V)= 0.553 +/- 0.056, yielding a distance modulus m -M_V of 15.537 +/- 0.212. In addition, it was found that the star GSC 3730_0797 in the field of NSV 01450 is also variable.
