Gaspar Jesús Melchor Flores Magón[1] (6 January 1871 – 7 December 1930) was a Mexican politician, journalist, and jurist.

The more moderate brother of Ricardo and Enrique Flores Magón, he served in the cabinet of Francisco I. Madero.

He graduated in law in 1897 and, in conjunction with his brother Ricardo, founded the newspaper Regeneración, the first edition of which appeared on 7 August 1900.

He was later expelled from the country for his anti-Porfirio Díaz writings; he fled to the United States where his political differences with his brothers – also exiled, and now espousing anarchist beliefs – deepened.

He returned to Mexico in 1910 following the overthrow of Porfirio Díaz in the early days of the Mexican Revolution.
