Abstract	Open questions on the fundamental nature of the strong force endure and the Large Hadron Collider (LHC) is a once-in-a-generation laboratory elucidating its quantum origins. These proceedings summarize the plenary talk "QCD Studies at the LHC" presented on behalf of the LHC collaborations at the Lepton Photon Symposium 2025. Selected results highlight recent experimental advances in Quantum Chromodynamics (QCD) at the LHC. This reviews the breadth of QCD and its cross-cutting synergies from a particle physics perspective in four themes: terascale precision tests, non-perturbative enigmas, mystery of confinement, and extreme cosmic-ray puzzles.
