This is a lecture that introduces the HR diagram. The HR diagram  is a plot of luminosity in solar units on the Y axis and stellar temperature on the X axis. The HR diagram is a key tool in tracing the evolution of stars. The lecture discusses the location of different stars on the diagram. It also includes a discussion of thermonuclear fusion and the neutrino problem. A quiz follows the lecture.
