Topological metaplasmonics represents an emerging field at the intersection of topological physics, plasmonics, and metamaterials, offering unprecedented opportunities for the robust control and manipulation of light at the nanoscale. This paper provides a comprehensive review of the fundamental principles, theoretical underpinnings, and experimental advancements in designing and realizing topological metaplasmonic systems. We delve into how the concepts of topological protection, originally discovered in condensed matter electronic systems, can be translated and applied to plasmonic platforms, leading to unidirectional, backscattering-immune light propagation and enhanced light-matter interactions. The integration of plasmonic metamaterials enables subwavelength light confinement and offers new degrees of freedom for engineering band structures and realizing non-trivial topological phases. We explore various topological phases, including those analogous to the quantum Hall, quantum spin Hall, and quantum valley Hall effects, and discuss their manifestation in plasmonic lattices, metasurfaces, and waveguide structures. The methodology section outlines the computational and experimental techniques crucial for the design, fabrication, and characterization of these complex systems. Furthermore, we highlight the enhanced robustness of topological plasmonic devices against defects and disorder, a critical advantage over conventional plasmonic systems. The discussion extends to potential applications in areas such as robust optical sensing, quantum information processing, nonlinear optics, and integrated nanophotonics, where the unique properties of topological metaplasmonics promise significant breakthroughs. This review underscores the transformative potential of topological metaplasmonics in creating next-generation light-matter interfaces with superior performance and resilience.
