ProtoDUNE-SP was a single-phase liquid argon time projection chamber - a prototype for the first far detector module of the Deep Underground Neutrino Experiment (DUNE) with an active volume of 700 tons operating until 2020. It was installed at the CERN Neutrino Platform and took particle beam and cosmic ray data over its two year lifespan. Liquid argon scintillation light is still an active subject of study with open questions about the impact of scattering and absorption in such a large detector. Here, we combine ProtoDUNE-SP cosmic-ray data with its large photon detector coverage and large drift volume to measure the Rayleigh scattering length of liquid argon. We also lay the groundwork for investigating Rayleigh scattering of scintillation light from xenon-doped liquid argon.
