Gregory Ignatius Zhatkovich[a] (December 2, 1886 – March 26, 1967) was an American lawyer and political activist for Rusyns in the United States and Europe.

He was born in Galambos, Bereg County, Austria-Hungary (now Holubyne, Svaliava Raion, Zakarpattia Oblast, Ukraine) and emigrated to Pennsylvania with his parents at age five.

Following his father's involvement in Rusyn affairs, Zhatkovich was drawn in 1918 into the role of a spokesman for the American National Council of Uhro-Rusyns, at the time when the dissolution of Austria-Hungary placed their future – as that of many other peoples – on the international diplomatic agenda.

[3] The declared reasons for his resignation were the unkept promises, dissatisfaction with the untruthful borders inside Czechoslovakia, but primarily the fact Tomáš Garrigue Masaryk did not want to grant autonomy to Carpathian Ruthenia.

He briefly served as a workmen’s compensation referee (judge) in 1934 and 1936, appointed by successive Pennsylvania Secretaries of Labor and Industry, first Charlotte Carr and subsequently Ralph Moody Bashore.

The book also asserts that the imperial interests which placed Zhatkovich in charge were mainly interested in using the territory as a conduit for arms and ammunition to the anti-Soviet Polish forces fighting the Polish-Soviet War of 1920, than going on directly to the north, and that Zhatkovich had to resign after failing to stop local Communists from holding strikes as well as repeatedly sabotaging the railway line from Prague, through which the munitions were passing.
