Low Head Lighthouse, Lighthouse at the mouth of the Tamar River, Low Head, Tasmania, Australia

Low Head Lighthouse is a cylindrical double-brick tower at the mouth of the Tamar River, painted white with a broad red band around its midsection since 1926. It has a glazed lantern room with a domed roof and white gallery railing, and four small windows down the front. The keeper's quarters were attached to the base, and a separate head keeper's house was built in 1890.

Colonel William Paterson installed a flagpole and fire beacon at Low Head in 1804, and after the Hebe wrecked on the reef in 1808 the Committee of Pilotage recommended a lightstation in 1826. Convict labour built the first tower, designed by John Lee Archer and lit on 27 December 1833 as Tasmania's second lighthouse. It was demolished in 1888 and replaced by Robert Huckson's double-brick tower, painted with a red band in 1926.

The tower's red band, painted on 5 January 1926, aids daytime recognition; the 1898 auxiliary light, made by Chance Brothers, shone red through a window about 6 metres below the main light to warn ships off Hebe Reef. The original 1833 apparatus came from W. Hart of Launceston: six dozen Argand lamps with tin reflectors at three shillings and sixpence each.

The tower stands on the east side of the Tamar River mouth, about 7 km north of George Town. The light is unmanned and automated, so the site is not staffed. The 1888 tower is double brick; the 1890 head keeper's quarters and the 1916 assistant keeper's quarters stand nearby, the latter to the southwest of the tower.

The red band was added on 5 January 1926 so the white tower could be seen by day. An 1898 auxiliary light, made by Chance Brothers, shines through a window about 6 metres below the main light to warn ships off Hebe Reef, where the Iron Baron grounded in 1995.
