lightship Columbiais a lightship located in Astoria, Oregon, United States of America. Columbia was formerly moored near the mouth of the Columbia River.

Commissioned in 1951, Columbia was the fourth and final lightship stationed at the mouth of the Columbia River. Built by Rice Brothers Shipyard in Boothbay, Maine, Columbia was launched with her sister-ship, Relief (WLV-605). The new WLV-604 replaced the aging Columbia vessel No. 90, which had been in service on the Columbia River since 1939. The Columbia River lightships guided vessels across the Columbia River Bar and an area known as the Graveyard of the Pacific from 1892 until 1979. Columbia was the final lightship to be decommissioned on the U.S. West coast. She was replaced by an automated navigational buoy soon after. The buoy has since been retired.

Now located at the Columbia River Maritime Museum, alongside the navigational buoy that replaced her in 1979.
