ABSTRACT COF@MXene composites are an emerging class of hybrid materials that integrate excellent electrical conductivity and chemical activity of MXenes with the structural tunability and porosity of covalent organic frameworks (COFs). This review outlines their synthesis strategies, structural features, and diverse applications in energy storage, environmental remediation, catalysis, and water treatment. The synergistic integration of COF@MXene enhances ion transport, active site exposure, and stability, enabling improved performance in lithium‐sulfur batteries, supercapacitors, hydrogen production, and pollutant removal. These hybrids also offer promising design flexibility for tailored applications. Key challenges related to fabrication, scalability, and interface control are discussed, along with potential pathways for industrial adoption. COF@MXene composites represent a significant step forward in developing multifunctional materials for next‐generation sustainable technologies. image
