亚历山大灯塔（阿拉伯语：منارة الإسكندرية‎；古希腊语：ὁ Φάρος τῆς Ἀλεξανδρείας）位于埃及的亚历山大港对面的法罗斯岛上，因此也叫做“法罗斯岛灯塔”，是古代世界七大奇迹之一。大约在前283年由小亚细亚的建筑师索斯特拉特设计，在托勒密王朝时建造。由于历史的模糊记载，预估高度115—140米之间（377—492英尺）。它在倒塌之前可能是仅次于胡夫金字塔和卡弗拉金字塔的第三高建筑物。

The Lighthouse of Alexandria, sometimes called the Pharos of Alexandria (/ˈfɛərɒs/; Ancient Greek: ὁ Φάρος τῆς Ἀλεξανδρείας), was a lighthouse built by the Ptolemaic Kingdom between 280 and 247 BC which was between 393 and 450 ft (120 and 137 m) tall. One of the Seven Wonders of the Ancient World, it was one of the tallest man-made structures in the world for many centuries. Badly damaged by three earthquakes between AD 956 and 1323, it then became an abandoned ruin. It was the third longest surviving ancient wonder (after the Mausoleum at Halicarnassus and the extant Great Pyramid of Giza) until 1480, when the last of its remnant stones were used to build the Citadel of Qaitbay on the site. In 1994, French archaeologists discovered some remains of the lighthouse on the floor of Alexandria's Eastern Harbour. The Ministry of State of Antiquities in Egypt has planned, as of late 2015, to turn submerged ruins of ancient Alexandria, including those of the Pharos, into an underwater museum.
