\abstract{Abstract}  Nanowires are one  of the fastest growing areas of study in the last decade due to their unique electronic, physical, and chemical properties. Gallium nitride is a semiconducting material that has been used in industry and research for its large bandgap, piezoelectric properties, and strength; the combination of both technologies to form gallium nitride nanowires has led to the development of next generation catalysts, probes, and electronics. This paper reviews the most recent developments in both efficient synthesis of gallium nitride nanowires as well as novel and optimized devices that utilize gallium nitride. The current trend in devices is the incorporation of various organic and inorganic materials for their synergistic effects. \section{Introduction}
