  Six of the principal galaxy distance indicators are discussed: Cepheid
variables, the Tully-Fisher relation, the Dn-sigma relation, Surface Brightness
Fluctuations, Brightest Cluster Galaxies, and Type Ia Supernovae. The role they
play in peculiar velocity surveys and Hubble constant determination is
emphasized. Past, present, and future efforts at constructing catalogs of
redshift-independent distances are described. The chapter concludes with a
qualitative overview of Malmquist and related biases.
