Övre Rudasjön (Swedish for "Upper Crucian carp Lake"), or Övre Rudan for short, is a lake in Haninge Municipality, 18 km (11 mi) south of central , Sweden. Forming part of the Tyresån Lake System, its major inflow comes from lakes Nedre Rudasjön ("Lower Crucian carp Lake") and Trylen to the south, while its outflow passes over Dammträsk into Drevviken to the north.

The proximity to the station at Handen, makes the lake easily accessible to a large number of people, while the forests surrounding it makes it attractive to open-air lovers.

With are 28 species of vascular plants by the lake and 1 species of Stoneworth in it, the lake fauna is considered relatively rich in species.
