Sir Frederick Palgrave Barlee KCMG (6 February 1827 – 8 August 1884) was Colonial Secretary of Western Australia from 1855 to 1875; Lieutenant-Governor of the British Honduras (now Belize) from 1877 to 1882; and Administrator of Trinidad in 1884.

He was educated privately and at local schools, and in 1845 he entered the public service as a clerk to the Ordnance Department in Chatham and Woolwich.

In 1853 he became clerk to the Executive and Legislative Councils, and private secretary to the Governor of Sierra Leone Arthur Edward Kennedy.

Both directly and through a newspaper that he had recently bought a stake in, Barlee agitated for responsible government, and in 1874 the Legislative Council passed a resolution calling for the constitutional change.

Although Weld did not think that Western Australia was yet ready for responsible government, he accepted the situation and passed on the request to the Colonial Office in London.

Barlee remained nominal colonial secretary for another eighteen months, and intended to return to the position unless he was offered a better appointment elsewhere.

Barlee arrived at Port of Spain, Trinidad and took up his appointment in June 1884, but died from asthma just seven weeks later on 8 August 1884.
