Chromospheric brightening and Hα surges are evident and common phenomena along sunspot light bridges. In this paper, a coronal jet ejection from a sunspot light bridge is presented. Using data from the Solar Dynamics Observatory and Hinode satellites, it is confirmed that the jet has its root near the light bridge. This suggests that the jet may be a result of reconnection between the main sunspot and the light bridge. Due to the processing of jet ejecta, the intensity and width of the light bridge show changes to some extent. This also suggests that the jet is related to the interaction between light bridge and umbra, possibly owing to magnetic reconnection or heated plasma trapped in the light bridge escaping and moving along field lines.
