begin{tex}New photometric (uvbyβ) observations of the intrinsic variable star V798 Cyg have been secured and used to derive values of foreground reddening, E(b - y) = 0\fm117, and metallicity, [Fe/H] = 0.64. Intrinsic (b - y) and c_{1} values indicate a mean effective temperature, < T_{eff} > = 7150 K, and a mean surface gravity, <logg> = 3.39. Pulsation theory and theoretical evolutionary tracks yield a mass of 2.3M_☉ and an age of 0.63 Gyrs. Although V798 Cyg has been described as being multi-periodic, this conclusion is not confirmed by our observations. V798 Cyg in most respects resembles a typical population I dwarf Cepheid.
