Mammen is a village in Viborg Municipality, Denmark 7 km north of Bjerringbro.

The Mammen area was the finding site of the famous and rich Mammen chamber tomb; a Viking Age chamber tomb, complete with the remains and offerings of a wealthy magnate burial in the winter of 970-71 AD.

The tomb was opened in 1868, when a farmer began digging away at the mound of Bjerringhøj.

[2] At about the same time, a hoard was unearthed close by in a gravel quarry.

[3] The various objects of both finds later gave name to the so-called Mammen style, an art phase typical of Scandinavia.
