Blencogo is a small farming village and former civil parish, now in the parish of Bromfield, in the Cumberland district, in the ceremonial county of Cumbria, England.

The village is a centre for growing osier willow for basketmaking and related crafts.

[1] Armstrong, et al. cite Ekwall,[2] who "derives this name from Welsh 'blaen' 'top'...and 'cog' 'cuckoo' to which was later added ON 'haugr' 'hill' ".

However, they say that it is more probable that the final element "is the British plural inflexion (Welsh '-au', Cornish '-ow', Breton '-ou')."

[4] Numerous land transfers are made to Holme Cultram Abbey in over the next 150 years.
