RR Lyrae stars are old, radially pulsating stars located on the horizontal branch which have long been used as cosmic distance indicators.  More recent work has shown that RR Lyrae are useful tools for studying a wide variety of topics in stellar, galactic, and extragalactic astronomy.  In this talk, I will discuss ongoing work in these different areas that is utilizing RR Lyrae and how these stars can be used to help identify substructures in the Milky Way halo, better understand how the halo was formed, and to look at mass transfer between binary stars.
