**Abstract.**
These proceedings summarize lectures that were delivered as part of
the 2002 and 2003 Theoretical Advanced Study Institutes in elementary
particle physics (TASI) at the University of Colorado at Boulder. They
are intended to provide a pedagogical introduction to cosmology aimed
at advanced graduate students in particle physics and string theory.
