Thomas Crosbie William Trevor, 22nd Baron Dacre (5 December 1808 – 26 February 1890) was a British landowner and politician.

Background Born Thomas Brand, Dacre was the eldest son of General Henry Trevor, 21st Baron Dacre, and Pyne, daughter of the Very Reverend Maurice Crosbie, Dean of Limerick. Henry Brand, 1st Viscount Hampden, Speaker of the House of Commons, was his younger brother. In 1824 he assumed by Royal licence the surname of Trevor in lieu of his patronymic. Educated at Christ Church, Oxford, he was a member of Boodle's, White's and Brooks' clubs.

Political career Dacre was returned to Parliament as one of three representatives for Hertfordshire in 1847, a seat he held until 1852. The following year he succeeded his father in the barony and entered the House of Lords. Between 1865 and 1869 he served as Lord Lieutenant of Essex.

He died at The Hoo, Hertfordshire, in February 1890, aged 81, and was succeeded in the barony by his younger brother, Lord Hampden. Lady Dacre died in August 1896, aged 79.
