  The Fornax Cluster is a conspicuous cluster of galaxies in the southern
hemisphere and the second largest collection of early-type galaxies within <~
20 Mpc after the Virgo Cluster. In this paper,we present a brief introduction
to the ACS Fornax Cluster Survey - a program to image, in the F475W (g_475) and
F850LP (z_850) bandpasses, 43 early-type galaxies in Fornax using the Advanced
Camera for Surveys (ACS) on the Hubble Space Telescope. Combined with a
companion survey of Virgo, the ACS Virgo Cluster Survey, this represents the
most comprehensive imaging survey to date of early-type galaxies in cluster
environments in terms of depth, spatial resolution, sample size and
homogeneity. We describe the selection of the program galaxies, their basic
properties, and the main science objectives of the survey which include the
measurement of luminosities, colors and structural parameters for globular
clusters associated with these galaxies, an analysis of their isophotal
properties and surface brightness profiles, and an accurate calibration of the
surface brightness fluctuation distance indicator. Finally, we discuss the data
reduction procedures adopted for the survey.
