William Duncombe, 2nd Baron Feversham (14 January 1798 – 11 February 1867), was a British peer with a large estate in the North Riding of Yorkshire.

He served as a Tory Member of Parliament (MP) for the Riding from 1832 to 1841, after which he sat in the House of Lords, having succeeded to the title on the death of his father.

When the colourful Radical MP Thomas Slingsby Duncombe died in 1861, it was noted in a piece appearing in a number of newspapers that The most comical contrast to Tom Duncombe was his cousin, the present Lord Feversham, a heavy, solid, goodnatured man, whose speeches are of the most ponderous and soporific character - "a man whose talk is of bullocks" and whose opinions were of the extreme Conservative and Protectionist colour.

[e] His final parliamentary speech was (in 1866) an attack on the inadequacy of the government's response to the current cattle plague outbreak:[20] Duncombe was a Tory; seconding the Loyal Address in 1822, he said that "the constitution stood so firm on its basis, was so beautifully connected in all its parts, and was so admirably adapted to all classes of society, that it was impossible but that all who enjoyed the blessing of living under it should perceive its advantages over any other system of government.

"[21] Consequently, Duncombe was opposed to the great liberal causes of his time (Catholic emancipation, parliamentary reform, abolition of the corn laws) but he did not seek to reverse them.

[22] Duncombe spoke at the great York Factory Reform meeting of 1832, despite his concern that his past political activity would taint the cause: he stressed 'this is not the cause of party..

[26] On Feversham's death in 1867, the Yorkshire Post noted that Oastler had "constantly alluded to the unfailing support he received from Lord Feversham in battling with the opponents of the bill as his principal mainstay and encouragement in the work they had undertaken"[15] Like Oastler, he opposed the Poor Law Amendment Act 1834: he voted against its Third Reading[27] (but he had been absent from all of the committee stage proceedings).

In 1838, he presented a petition from Huddersfield supporting the refusal of its magistrates to call out the military to suppress anti-Poor Law disturbances[31] in which Oastler had been prominent.

Tennyson asserted his constituents had represented to him the need for both members for the seat to hold similar views; acceding to their wishes he had selected Duncombe as his running mate.

In 1825 Duncombe was called upon to stand for election as a 'firm upholder of the Protestant cause' (opponent of Catholic emancipation) in the prestigious four-member county constituency of Yorkshire.

In the 1831 general election, Duncombe was again requisitioned to stand: he accepted the invitation, but withdrew before the actual poll, it being clear that Reform candidates would take all four seats.

In December 1832 he headed the poll ahead of two competing Reformers;[43] John Charles Ramsden (supported by the Whig grandees) a West Riding industrialist and former Whig MP for Yorkshire, and Edward Stillingfleet Cayley, an independent of Liberal sympathies who farmed locally and put himself forward as a friend of the interests of small agriculturalists: Cayley took the second seat.

Children: The Grade II* listed Feversham Monument, "erected by his tenantry, friends and relations, who cherish his memory with affection and gratitude" stands in the middle of the market square of Helmsley, North Yorkshire.
