Constantin Gheorghe Costa-Foru (26 October 1856 – 15 August 1935) was a Romanian journalist, lawyer, and human rights activist.
In 1740 they had settled in Bucharest, where they amassed considerable wealth, building a mansion in Popești-Leordeni and summer residence was in Berca.
After finishing his studies he returned to Paris, where he married with Maria Ion Paspatti (1872–1935) on 26 June 1893.
Constantin Costa-Foru was a vocal supporter of human rights, and accused the growing antisemitism in the post–World War I Romania.
As a lawyer he pleaded, in 1925 at Turnu-Severin, against nationalist Corneliu Zelea Codreanu, leader of the anti-Semite Iron Guard, who had assassinated the prefect of Iași.
