  We present the detection of Cepheids in the barred spiral galaxy NGC 1313,
using the Wide Field and Planetary Camera 2 on the Hubble Space Telescpoe.
Twenty B (F450W) and V (F555W) epochs of observations spanning over three weeks
were obtained, on which the profile-fitting photometry of all stars in the
monitored field was performed using the package HSTphot. A sample of 26
variable stars have been identified to be Cepheids, with periods between 3 and
14 days. Based on the derived period-luminosity relations in B and V bands, we
obtain an extinction-corrected distance modulus of mu = 28.32 +- 0.08 (random)
+- 0.06 (systematic), employing the Large Magellanic Cloud as the distance zero
point calibrator. The above moduli correspond to a distance of 4.61 +- 0.17
(random) +- 0.13 (systematic) Mpc, consistent with previous measurements
reported in the literature with uncertainties. In addition, the reddening to
NGC 1313 is found to be small.
