On the last day of 1944, "Alcyone" sortied with TG 79.4, for the assault on the Lingayen beaches which began on 9 January 1945. The task of unloading her cargo was made more difficult by rough seas, Japanese suicide boat attacks, and enemy air raids. "Alcyone" remained in the area for five days before she finished emptying her holds. On the 13th, she set a course for Leyte where she replenished her stores before returning to Luzon on the 29th with a small attacking force for a landing at Zambales. The assault was unopposed, and operations were completed on 31 January.
