Alby is a village on the Baltic Sea in the Hulterstad district at the western fringe of the Stora Alvaret.

Archaeological evidence indicates this settlement to have been one of the oldest on the island of Öland, with excavations, dating to the paleolithic era, showing the presence of hunter-gatherers.

The village prehistory dates to the early Stone Age when settlers from the mainland migrated across the ice bridge connecting the island via the Kalmar Strait about 6000 to 7000 BC.

These early inhabitants are known in the archaeological literature as the Alby.
