West Cumberland was a county constituency in the House of Commons of the Parliament of the United Kingdom.

The parliamentary boroughs included in the West division, between 1832 and 1885, (whose non-resident 40 shilling freeholders voted in the county constituency) were Cockermouth and Whitehaven.

It may be that these economic and demographic developments made the Liberals, critical of the remnant Anglican ascendancy, more competitive by 1880 than they had been earlier in the century.

In addition there were two remaining Cumberland borough constituencies; Carlisle and Whitehaven.

Note:- Lowther was also elected for Westmorland and opted to sit there, causing a by-election.
