The MRTC 3100 class or CRRC Dalian 8MLB LRV is the class of second-generation uni-directional light rail vehicles (LRVs) built by CRRC Dalian. Owned by the Philippine government and operated by the Department of Transportation (DOTr), these are used on Line 3 of the Manila Metro Rail Transit System since 2016.

The trains were involved in legal issues and numerous controversies owing to its weight and incompatibility with the existing system, which the Metro Rail Transit Corporation (MRTC) raised that same year. The trains remained idle as these issues persisted, but in 2018, limited deployment commenced. It was repeatedly pulled from service and deployed erratically between 2019 and 2022, before being revived for regular operations in 2025.
