Umpqua River Light, Lighthouse in Winchester Bay, United States.

Umpqua River Light is a red brick lighthouse standing on a coastal bluff above Winchester Bay in Douglas County, Oregon, rising about 65 feet (20 meters) tall. Inside, a large Fresnel lens rotates and casts red and white beams across the water.

The first Umpqua River Light was built in 1855 and lit in 1857 along the river channel, where seasonal flooding eroded its sand embankment. Its foundations failed and it collapsed in October 1863. Congress approved a replacement in 1888; construction began in 1892 and the new light was first lit in 1894, built from the same plans as Heceta Head Light.

The museum in a former Coast Guard building displays ships' equipment, navigation tools, and old maps that show how fishermen and sailors once used these waters. The collection tells the story of people who worked daily with the sea.

The tower is generally open to visitors between May and October, and those who want to go up should be comfortable climbing a very narrow spiral staircase. The space at the top is tight, so the climb may not suit everyone.

The Fresnel lens still turns on its original clockwork mechanism, which ran for 89 years before breaking down. When the Coast Guard planned to replace it, public protest stopped the swap, and in 1985 the restored mechanism went back into place.
