The distance to NGC 3319 has been determined from Cepheid variable stars aspart of the Hubble Space Telescope Key Project on the Extragalactic DistanceScale. Thirteen and four epochs of observations, using filters F555W (V) andF814W (I) respectively, were made with the Wide Field Planetary Camera 2.Thirty-three Cepheid variables between periods of 8 and 47 days werediscovered. Adopting a Large Magellanic Cloud distance modulus of 18.50 +- 0.10mag and extinction of E(V-I)=0.13 mag, a true reddening-corrected distancemodulus (based on an analysis employing the ALLFRAME software package) of 30.78+- 0.14 (random) +- 0.10 (systematic) mag and the extinction of E(V-I) = 0.06mag were determined for NGC 3319. This galaxy is the last galaxy observed forthe HST H0 Key Project.
