Tenuous, dusty debris disks around main-sequence stars hold clues to the evolution and architecture of planetary systems. With the unprecedented sensitivity of the Atacama Large Millimeter/Submillimeter Array (ALMA), we are now able to study the spatial distribution of large dust grains in debris disks at a high level of precision, as well as investigating the surprising presence of gas disks that persist well past the protoplanetary disk stage. I will review recent observations of gas and dust in debris disks with ALMA, discuss how these observations contribute to a multiwavelength picture of the physics sculpting dust grains of different sizes, and review the implications of these results for our understanding of the underlying structure and evolution of planetary systems.
