The Tran Dai Nghia (HQ-888) is a hydrographic survey vessel operated by the Vietnam People's Navy, built to the Damen Hydrographic Survey Vessel 6613 (HSV 6613) design.

Named after the prominent Vietnamese military scientist Trần Đại Nghĩa, the ship actively conducts underwater mapping, scientific research, and search and rescue operations in the South China Sea.
