Point Adams Light was a lighthouse near the mouth of the Columbia River on the Oregon Coast of the United States. It was designed by Paul J. Pelz. It operated from February 15, 1875 until 1899, when it became obsolete by the extension of the south jetty and the establishment of the Lightship Columbia in 1892. The lighthouse was considered a fire hazard and demolished in 1912.
It was located about a mile south of Point Adams—named by Captain Robert Gray in 1792 —near what is now Battery Russell in Fort Stevens State Park. The combination of the Point Adams Light with the Cape Disappointment Lighthouse on the north side of the river effectively framed the entrance to the Columbia.
The keeper's quarters and light were a combined structure, similar to the Yaquina Bay Light, in Newport, and used the same structure, materials, and optics as Point Fermin Light south of Los Angeles, California.
The light was changed from alternating red and white to fixed red on January 21, 1881 to reduce confusion with the nearby just-completed Tillamook Rock Light. The change caused HMS Fern Glen to run aground, evidently unaware of the change. At the same time, the fog signal was removed: it had long been criticized by mariners as being inaudible over waves crashing on shore.
The keeper considered the biggest maintenance problem to be the prevention of sand accumulation at the base of the lighthouse. Fences were unsuccessfully attempted at one point.
