Bernardo Reyes (August 1850 – February 3, 1913) was a General in the army of Mexico under Porfirio Díaz. He served as governor of Nuevo León he helped in the modernization of that state. While governor of Nuevo León, Reyes approved a workers compensation law. He was the father of the writer Alfonso Reyes, and grandfather of the painter Aurora Reyes. Followers of Reyes were known as Reyistas.
Due to his opposition to some of Díaz's policies, Reyes was sent on a diplomatic mission to Europe to prevent him from causing problems in Mexico.
Together with José Yves Limantour, he was considered as one of the potential successors of Porfirio Díaz. With Francisco Madero's latter challenge to the dictator in the 1910 elections and, afterwards, initiation of the Mexican Revolution, previous notions of who should succeed Díaz were discarded.
For a time Reyes was a supporter of Madero, but he later led the first rebellion against Madero. After this rebellion failed, Reyes was imprisoned.
In 1913, Manuel Mondragón's forces freed Reyes from prison. Then, they marched on to the National Palace in the beginning of the Decena trágica. Reyes was killed in the initial assault on the palace.
