'''Dellen''' is a [[lake]] system in the [[provinces of Sweden|province]] of [[Hälsingland]], [[Sweden]]. It consists of two lakes, ''Northern Dellen'' and ''Southern Dellen'', appreciated among fly-fishermen for their distinct population of [[brown trout]].
Southern Dellen has a surface area of 52 km² and a water volume of 1,226 million m³.
Northern Dellen has an area of 82 km² and a water volume of 1,489 million m³.
The two lakes are only united by a short channel so it is disputed whether they should be counted as one or two lakes. If counted together, it would have a total area of 130 km², making it the 18th largest [[Lakes of Sweden|Swedish lake]].
The vaguely circular lake system was formed by a [[meteorite]] [[impact crater|impact]] 89.0 ± 2.7 [[million]] [[year]]s ago placing it in the Upper [[Cretaceous]]. The resulting impact crater measures about 19 [[kilometre]]s in diameter. It has resulted in the area containing the rock [[Dellenite]], which has become the provincial rock of the province.
[[Asteroid]] [[7704 Dellen]] was named after it.
