Intrinsically chiral plasmonic nanomaterials exhibit intriguing geometry‐dependent chiroptical properties, which is due to the combination of plasmonic features with geometric chirality. Thus, chiral plasmonic nanomaterials have become promising candidates for applications in biosensing, asymmetric catalysis, biomedicine, photonics, etc. Recent advances in geometric control and optical tuning of intrinsically chiral plasmonic nanomaterials have further opened up a unique opportunity for their widespread applications in many emerging technological areas. Here, we review the recent developments in the geometric control of chiral plasmonic nanomaterials with special attention given to the quantitative understanding of the chiroptical structure‐property relationship. We also discuss several important optical spectroscopic tools for characterizing the optical chirality of plasmonic nanomaterials at both ensemble and single‐particle levels. We further highlight three emerging applications of chiral plasmonic nanomaterials including enantioselective sensing, enantioselective catalysis, and biomedicine. We envision that these advanced studies in chiral plasmonic nanomaterials will pave the way toward the rational design of chiral nanomaterials with desired optical properties for diverse emerging technological applications.
