Emil Byk (born January 14, 1845, at Janów (now Ukrainian: Dolyna), nearby Trembowla (Ukrainian: Terebovlia), in Austrian Galicia (now Ukraine) - 1906) was a Polish-Austrian-Jewish lawyer and deputy.
In 1885 he was chosen the chairman of the charity committee of the Cultusrath (German: Kultusrat, Board of Education) of Lemberg, and in 1902 became president of the Jewish community there. In 1890 he was a "Stadtverordneter" and president of the Shomer Israel Society. In 1891 he was elected to represent Brody and Zolochiv in the Reichsrat.
Some of his more important speeches in that body were:
an address in 1893, against Prince Liechtenstein on the establishment of a Jewish theological seminary.
an address, May 4, 1898, against the proposition that the sittings of the committee to consider the charges against ex-Prime Minister Kazimierz F. Graf Badeni should be public
1898 address on the "Ausnahmeszustand" (state of emergency)
in Galicia, which was very well received.
