William Herbert, 2nd Earl of Pembroke (5 March 1451 – 16 July 1491) was an English nobleman and politician.

Awarding lands in the south-west of England meant that Edward had moved the family influence out of Wales.

After the rebellion of 1483 he received the post of Chief Justice of South Wales, which had been the Duke of Buckingham's.

[3] After his marriage to his second wife, Katherine, an illegitimate daughter of Richard III in 1484, he received an annuity of some £1,000 a year, nearly doubling his income.

[4][3] Katherine is presumed to have died by 1487, because when William participated in the coronation of his first wife's niece, Elizabeth of York, he was noted to have been a widower.
