Stora Rängen, Freshwater lake in Linköping Municipality, Sweden.

Stora Rängen is a lake in Linköping Municipality, about ten kilometres south of Linköping, with an area of 10.9 square kilometres and a maximum depth of 23 metres at the Vessers udde nature reserve. It is the municipality's third-largest lake after Roxen and Järnlunden. Its shoreline is varied, with many islands, headlands and bays, and the water is of good quality though slightly coloured.

The lake was long called Kinden because it was counted as part of Småland. During the construction of the Kinda Canal in the 1850s, the water level was lowered to its present height of 84.1 metres above sea level.

The lake was long called Kinden because it was counted as part of Småland. On the eastern shore stands Bjärka Säby Castle, and the western shore has Stavsäter estate; the surrounding oak landscape is most evident around Bjärka Säby. The village of Bestorp lies at the southeastern end.

Stora Rängen lies about ten kilometres south of Linköping, with Bestorp at its south-eastern end and the Svartmåla cottage area on the western shore. Kinda Canal enters from Lilla Rängen in the south and leaves in the north, both naturally via Stångån and through the canal. The water is good but somewhat coloured, and the greatest depth, 23 metres, is off the Vessers udde nature reserve.

The lake receives water from about 99 smaller tributary areas, highlighting its role as an important water system for the surrounding region. These many connections make it a complex water network that extends far beyond its visible borders.
