  We report the discovery of the first identified pulsating DA white dwarf in
the field of the Kepler mission, WD J1916+3938 (Kepler ID 4552982). This ZZ
Ceti star was first identified through ground-based, time-series photometry,
and follow-up spectroscopy confirm it is a hydrogen-atmosphere white dwarf with
an effective temperature = 11,129 $\pm$ 115 K and log g = 8.34 $\pm$ 0.06,
placing it within the empirical ZZ Ceti instability strip. The object shows up
to 0.5 percent amplitude variability at several periods between 800 -- 1450 s.
Extended Kepler observations of this object could yield the best lightcurve,
to-date, of any pulsating white dwarf, allowing us to directly study the
interior of an evolved object representative of the fate of the majority of
stars in our Galaxy.
