  These notes introduce basic aspects of black hole thermodynamics. I review
the classical laws of black hole mechanics, give a brief introduction to the
essential concepts of quantum field theory in curved spacetime, and derive the
Unruh and Hawking effects. I conclude with a discussion of entropy from the
Euclidean path integral point of view and in the context of the AdS/CFT
correspondence. Originally delivered as a set of lectures at the PIMS summer
school ``Strings, Gravity and Cosmology'' in August 2004.
