Existing and new observations of the variable V480 Lyr are examined and analyzed. This study utilized a 25-cm Schmidt-Cassegrain Telescope (SCT) to observe multiple cycles of the star and obtain new BVRI-band photometry. These new observations, when combined with other published observational data, allowed the determination of multiple period values for the variable. From this multi-period behavior, and from an examination of other intrinsic parameters, there is evidence that V480 Lyr could be classified as an RV Tauri type star, which differs from earlier classifications.
