Gabriel Fabrero Fabella (March 18, 1898 – January 29, 1982) was a prominent Filipino historian during the 20th century. He is primarily known as the historian behind Philippine President Diosdado Macapagal's decision to issue Proclamation No. 28 on May 12, 1962, which changed the date of Philippine independence from July 4, 1946 to June 12, 1898 — the date when Philippine President Emilio Aguinaldo proclaimed the country's independence from Spain in Kawit, Cavite. For this achievement, Fabella became known as the "Father of June 12 Independence Day."
