Tree Point Light, Lighthouse in Prince of Wales-Hyder Census Area, Alaska.

Tree Point Light is a lighthouse on the southeastern coast of Alaska featuring a white concrete tower approximately 86 feet high with a red beacon and Art Deco design details. The structure serves to guide ships through the Revillagigedo Channel and remains fully functional for maritime navigation.

The first light station was established in 1904 by the United States Lighthouse Service to guide ships through this hazardous coastal area. A complete reconstruction using reinforced concrete took place in 1935, creating the structure that stands today.

The name comes from the surrounding Tongass National Forest: "Tree Point" refers to the wooded site. The station's 2003 NRHP nomination calls it the most intact lighthouse outpost in southern Southeast Alaska, and the listing covers the 1935 concrete light and fog-signal building, a keeper's residence, two original oil houses, a later boathouse and water-supply features.

The station stands on the mainland shore of Revillagigedo Channel near Alaska's southernmost mainland point, with no road to the site; access is by boat or floatplane from Ketchikan. The 2003 NRHP listing notes a tramway run, a boathouse and a water-supply system, so expect wet, foggy coastal weather at any season.

The fourth-order Fresnel lens installed in the 1935 lighthouse was removed after automation in 1969 and is now displayed at the Tongass Historical Museum in Ketchikan. In 1977 a solar-powered VRB-25 Vega lens was placed back inside the lantern room.
