The Alpe is a river of Lower Saxony, Germany.

The Alpe is a left tributary of the Aller. Its source lies between the villages of Dudensen and Nöpke [de; eo; nl], both within the town of Neustadt am Rübenberge. It initially crosses the Dudensen Bog and flows along the edge of the Bog Lichtenmoor [ceb; de] and past Rethem Bog. In the 1970s it lost its natural character, it was straightened and, in places, canalised. The Steimbker Dorfgraben, a drainage ditch joining it from the left, is very heavily polluted (water quality class III–IV). The Alpe itself has a good overall water quality (class II = moderately polluted). Before the town of Rethem the Weiße Graben ("White Ditch") joins the Alpe along with the Wölpe. In Rethem the Alpe then discharges into the Aller.
