In this talk, I will discuss the intersection of binary formation and planet formation from various perspectives. First, I will consider the formation of objects whose observational properties confound the theorists trying to form them, and the observers trying to classify them. I will then move on to discuss the formation and architecture of binary star systems that host planetary systems. I will focus on circumbinary planets around main-sequence stars. I will explain why young, tight binaries pose a conundrum for theories of star formation, and why their planets may provide strong constraints on their formation history. Finally, I will review the dynamics of our own local circumbinary planetary system: the Pluto-Charon satellite system, and connect it to recent exoplanet discoveries.
