        abstract = {Hybrid Fiber-Reinforced Concrete (HFRC) has emerged as an effective construction material because it offers higher strength, better durability, improved ductility, and greater crack resistance than conventional concrete. This review examines the performance of concrete reinforced with both natural fibers, such as coconut coir and bamboo, and synthetic fibers, including glass, polypropylene, steel, carbon, and Kevlar fibers. Previous studies show that hybrid fibers significantly improve compressive strength, tensile strength, flexural strength, toughness, impact resistance, and energy absorption capacity. Different fibers work together to control both microcracks and macrocracks, which reduces brittleness and improves post-cracking behavior. Natural fibers support sustainable construction due to their renewable and biodegradable properties, while synthetic fibers enhance strength, stiffness, and long-term durability. The literature also shows that fiber content, aspect ratio, fiber length, and fiber combinations strongly affect the overall performance of HFRC. Optimizing the fiber content in hybrid fiber-reinforced concrete enhances structural performance while ensuring adequate workability and uniform dispersion of fibers within the concrete matrix. HFRC demonstrates significant potential for use in reinforced concrete beams, pavements, repair and rehabilitation projects, precast concrete units, and other high-performance structural applications. This review summarizes key findings from prior studies, presents recent advances in HFRC technology, and emphasizes the need for further research on long-term durability, economic feasibility, and practical large-scale implementation in structural engineering applications.},
