High‐performance single‐photon light detection and ranging (LiDAR) technology with robust noise resistance provides a powerful means for environmental perception in extreme scenarios. Here, we propose a parallel photon‐correlation (PPC) LiDAR driven by super‐bunching light, enabling noise‐resistant parallel detection in the single‐photon‐counting regime. Using super‐bunching light with g (2) (0) = 177, we demonstrate robust photon‐correlation imaging at a signal‐to‐background ratio (SBR) of 1:2750 in the 2D parallel imaging experiment, and also achieve noise‐resistant three‐dimensional (3D) target reconstruction. Leveraging the correlation between the reference and echo signals, PPC LiDAR enables parallel ranging up to 165 m in a single‐channel, beyond the distance threshold limited by the pulse period. In the outdoor imaging experiment, parallel imaging over 40 m was achieved. By combining 10‐channel parallel detection with robust noise resistance, PPC LiDAR provides a light‐source‐based solution for single‐photon LiDAR operation under extreme conditions, distinct from experimental quantum illumination. Our PPC LiDAR scheme opens a new pathway toward the next generation of high‐performance environmental perception technology.
