The early medieval period is sparsely represented in Tullie House's collection. The most significant part of the collection is two Viking burials, one from Ormside and the other from Hesket-in-the-Forest. These were both discovered in the 19th century. Other burial material includes that from Eaglesfield, near Aspatria.

Other Viking material is mainly made up of single items. However, as soon as the excavation report is completed, a collection of finds from an excavation at Cumwhitton will join the collection. This is a series of burials, including one that had large oval brooches, providing evidence for Viking women in Cumbria for the first time.
