Sir Francis Tress Barry, 1st Baronet (1825 – 28 February 1907) was an English businessman who made his fortune from a copper mine in Portugal. Late in his life he became a Conservative Party politician to England, and sat in the Commons from 1890 to 1906.
Barry was born in 1825, the eldest son of Charles Barry from Orpington, Kent. He was educated in London at Camberwell Collegiate School. In 1851 he married Sarah Douglas, the daughter of Arthur Herron from Northiam in Sussex. The couple had four sons and two daughters, and celebrated their golden wedding in 1901.
Leaving school at the age of 16, Barry went to Spain to work in a business in Bilbao. He became the British vice-consul for the Biscay province in 1846, and the following year he served as temporary consul for the Biscay, Santander and Guipúzcoa provinces.
In the 1850s he was offered the post of consul in Madrid, but turned down the job to concentrate in his business interests. He returned to England, where he joined with his brother-in-law James Mason to take a 50-year lease on the Sao Domingos copper mine in Portugal. They switched production technique to opencast mining, and made large profits.
In 1863 was awarded the Order of Christ by King Luís I of Portugal, was promoted to Commander of that order in 1868, and ennobled as Baron de Barry in 1873. He also received the Cross of Naval Merit from the King of Spain.
