Repeated imaging observations of NGC 4395 were made with the WIYN 3.5 m and the KPNO 2.1 m telescopes. From the photometry of the resolved brighter stars in this galaxy, 11 Cepheids with periods ranging between 12 and 90 days have been identified. The true distance modulus has been derived from the apparent distance moduli in g, r, and i. The distance modulus is 28.02±0.18 based on the LMC period-luminosity (P-L) relation of Sandage, Reindl, & Tammann; this corresponds to a distance of 4.0±0.3 Mpc. Using the P-L relation from Madore & Freedman, the distance modulus is 28.15±0.18, which corresponds to a distance of 4.3±0.4 Mpc. The reddening is calculated to be E(g-r)=0.06±0.08 and E(r-i)=0.10±0.08, again from the distance moduli µ_g, µ_r, and µ_i. In addition, 37 other variables have been detected, the majority of which have definite periods; they are probably all red long-period variables.
