Henry Nevill, 2nd Earl of Abergavenny, KT (22 February 1755 – 27 March 1843) was a British peer, styled Hon.

Nevill was also nominated, without his knowledge, as the candidate for Seaford on the Treasury interest and was returned there after a contest, together with Sir Peter Parker, on 30 March 1784.

[3] The losing candidates, Lewis Watson and Thomas Alves, were supported by the Pelham family, led by the Duke of Newcastle.

While he generally followed the lead of his father-in-law, John Robinson in supporting Pitt's administration, he is known to have broken with them on some issues, such as the scrutiny of the Westminster election of 1784.

In 1795 he objected to the regiment's winter quarters at Devizes as being too cold for Lady Abergavenny, and they were shifted to Lymington, which he found warmer.
