Naval Base Lingayen was a United States Navy base built during World War II at Lingayen Gulf on the northwestern Island of Luzon in the Philippines. The base was founded after the Invasion of Lingayen Gulf on January 9, 1945, at Lingayen city and the surrounding gulf. The Naval base was used to support the later operations at Manila and the rest of Luzon Island and then at Okinawa. Lingayen Gulf offered excellent fleet anchorage.

US Navy Seabee pontoon battalion landed with the troops at Lingayen on January 9, 1945. The Seabee task was building pontoon piers out into Lingayen Gulf so the massive about of supplies needed for the invasion could be unloaded quickly. Over 90% of the invasion supplies were unloaded on the pontoon piers. Seabee built a Naval Base Headquarters at the city of San Fernando on the north east side of Lingayen Gulf. A supply depot was built at Lingayen, US Navy Advance Base 6. The US Army had its Headquarters at San Fernando also, called Base M. The Army had a number of camps around Lingayen Gulf.
