  We report on the discovery of Cepheids in the spiral galaxy NGC 2841, based
on observations made with the Wide Field and Planetary Camera 2 on board the
Hubble Space Telescope. NGC 2841 was observed over 12 epochs using the F555W
filter, and over 5 epochs using the F814W filter. Photometry was performed
using the DAOPHOT/ALLFRAME package.
  We discovered a total of 29 variables, including 18 high-quality Cepheids
with periods ranging from 15 to 40 days. Period-luminosity relations in the V
and I bands, based on the high-quality Cepheids, yield an extinction-corrected
distance modulus of 30.74 +/- 0.23 mag, which corresponds to a distance of 14.1
+/- 1.5 Mpc. Our distance is based on an assumed LMC distance modulus of 18.50
+/- 0.10 mag (D = 50+/- 2.5 kpc) and a metallicity dependence of the Cepheid
P-L relation of gamma (VI) = -0.2 +/- 0.2 mag/dex.
