George J. Willmann (June 29, 1897 - September 14, 1977) was a Jesuit regarded as the "Father of the Knights of Columbus in the Philippines".

Born in the United States, he was granted Filipino citizenship due to his missionary work in the Philippines.

[1] Willmann came to the Philippines in 1922 as a seminarian to accomplish a teaching stint at the Ateneo de Manila and later returned to the United States in 1925 to continue his theological studies.

[1][2] On June 20, 1928, Willmann was ordained at the Woodstock College in Maryland by Archbishop Michael Joseph Curley.

[1][2] Servicemen clubs were established under the guidance of the Army-Navy Morale Committee, which Willmann and the auxiliary bishop of Manila, Rufino Santos, were members of in December 1941.

[1][3] On July 1, 1975, Willmann was granted Filipino citizenship by then President Ferdinand Marcos through Presidential Decree No.

He also helped established the presence of various organization in the country such as the Daughters of Mary Immaculate (DMI) which was established as the Daughters of Isabella in 1951, Knights of Columbus Fraternal Association in the Philippines, Inc (KCFAPI), KC Foundations, Columbian Squires, and the Catholic Youth Organization (CYO).

[4][7] The National Executive Committee, led by former Chief Justice Hilario Davide, Jr. and Pedro C. Quitorio as Vice-Chairman, was created to campaign for Willmann's beatification which may lead to the priest's sainthood.
