William King-Noel, 1st Earl of Lovelace, FRS (21 February 1805 – 29 December 1893), styled The Lord King from 1833 to 1838, was an English nobleman and scientist.

He was created Viscount Ockham and Earl of Lovelace in 1838, and appointed Lord Lieutenant of Surrey in 1840, a post he held until his death.

In 1860, the Earl's eldest son, Byron, succeeded his maternal grandmother to become 12th Baron Wentworth according to its special remainder.

Lord Lovelace had three homes: Ockham Park, Surrey; Ben Damph Estate on Loch Torridon in Ross-shire; and a house in London.

In 1886, the Earl purchased Ben Damph Lodge and its surrounding 12,000 acre sporting estate at the east end of Loch Torridon,[8][9] in Ross-shire, Scotland.

The first Earl of Lovelace was buried in his mausoleum in the churchyard of Martin's Church, East Horsley, which still contains his tomb and that of his second wife.
