Ferdinand Johann Franz Blumentritt (10 September 1853, Prague – 20 September 1913, Litoměřice) was an Austrian teacher, secondary school principal in Leitmeritz, lecturer, and author of articles and books about the Philippines and its ethnography.

Blumentritt was born in Prague (now the Czech Republic, then the capital of Kingdom of Bohemia in the former Austrian Empire).

Blumentritt wrote extensively about the Philippines, although he never visited the islands, corresponding with the then Filipino student and writer José Rizal, who later became a national hero.

These two novels are commentaries disguised as fiction which angered both the Catholic Church and the Spanish colonial government, and which eventually led to Rizal's 1896 trial and execution.

Alongside Rizal, Blumentritt was a significant contributor to the publication La Solidaridad, published by Filipino expatriates from 1889 to 1895 as a voice for advocacy of political reforms in the Philippines.
