Alexandra, informally abbreviated to Alex, is a township in the Gauteng province of South Africa. It forms part of the City of Johannesburg Metropolitan Municipality and is located next to the wealthy suburb of Sandton. Alexandra is bounded by Wynberg on the west, Marlboro and Kelvin on the north, Kew, Lombardy West and Lombardy East on the south. Alexandra is one of the poorest urban areas in the country. Alexandra is situated on the banks of the Jukskei River. In addition to its original, reasonably well-built houses, it also has a large number of informal dwellings or "shacks" called imikhukhu.
