Recent progress in metamaterial research has successfully exceeded the limitations imposed by conventional materials and optical devices, enabling the manipulation of electromagnetic waves as desired. The distinct characteristics and controlling abilities of metamaterials make them ideal candidates for novel photonics devices not only in traditional optics but also for biological detection, medical science, and metrology. However, the controllability and functionality of both single‐layer metasurfaces and bulk metamaterials are not sufficient to meet the requirements of emerging technologies; hence, new solutions must be found. As such technologies advance, new functionalities will emerge as different or identical single‐layer metasurfaces are combined. Thus, innovation in few‐layer metasurfaces will become an increasingly important line of research. Here, these metasurfaces are classified according to their functionalities and the few‐layer metasurfaces that have been proposed up to now are presented in a clear sequence. It is expected that, with further development in this area, few‐layer metasurfaces will play an important role in the family of optical materials.
