Most stars occur in binary systems, and this may have a crucial effect on the intrinsic and observed properties of planets. Binarity may suppress planet formation, modify the orbits of planets that do get dragged into existence, and confound our attempts to measure their physical properties. I present a suite of high-resolution imaging studies of the host stars of transiting planets to demonstrate and explore these points. Conversely, stellar multiplicity may open new ways of understanding planetary systems. I present the discovery of a white dwarf and a low-mass eclipsing binary, both bound to planetary systems discovered by the SuperWASP survey.
