Plasmonic nanostructures can enhance light\u2013matter interaction; however, most reported devices rely on complex nano\/microfabrication processes, which increases cost and limits scalability. Here, we demonstrate a NIR graphene photodetector enhanced by disordered percolated Au nanostructures through a simple fabrication process. The disordered Au nanostructures support broadband plasmonic absorption over 1200\u20131600 nm, producing strong local electromagnetic fields and facilitating hot-carrier generation. Spatially resolved photocurrent mapping, illumination-dependent transfer characteristics, and electromagnetic simulations support plasmon-induced hot-carrier injection from the Au nanostructures into graphene as an important contribution to the observed photoresponse. The resulting photoinduced carrier redistribution creates a potential difference between the Au-covered and uncovered graphene regions, providing the internal driving force for carrier transport at zero source\u2013drain bias. The device exhibits a broadband zero-bias photoresponse over 1200\u20131600 nm, with a maximum voltage responsivity of approximately 20 mV W\n                    <jats:sup>\u22121<\/jats:sup>\n                    .
