The Carvetii were one of the Celtic tribes living in the British Islands, previous to the Roman invasion of Britain. The tribe lived in the northern England, namely in modern Cumbria and Lancashire, centred around the capital Carvetiorum. They were probably a tribe included in the confederation of the Brigantes.
Venutius, husband of Cartimandua, the queen of the Brigantes, and later an important British resistance leader, may have been a Carvetian.
Interestingly, the Carvetii are not mentioned in the Geography of Claudius Ptolemaeus.
The tribe's omission from the work of Ptolemy, the major historical source of the names of indigenous tribes, has meant that the Carvetii were not certainly identified until an inscribed Roman tombstone was found in 1600 at Old Penrith.
The new governor was forced to send several cohorts to her aid, until the forces under the able command of Venutius were eventually defeated in a decisive engagement.
