Gaspar Jesús Melchor Flores Magón (6 January 1871 – 7 December 1930) was a Mexican politician, journalist, and jurist. The more moderate middle brother of Ricardo and Enrique Flores Magón, he served in the cabinet of Francisco I. Madero.

Jesús Flores Magón was born in San Jerónimo Tecóatl in the state of Oaxaca in 1871, to Margarita Magón and Teodoro Flores, a Nahau who had fought in Benito Juárez's Liberal Army. At an early age the family relocated to Mexico City.

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. As editor of the paper, he was jailed on several occasions for criticising the judicial system. 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.
