José María Estrada Reyes (1802 – 13 August 1856 in Ocotal) was the President of Nicaragua after Fruto Chamorro’s death during the Filibuster War, serving from 12 March to 23 October 1855.

He was ratified as the provisional president of the Legitimists on 10 April 1855, a month after Chamorro's death.

In disgust of the efforts of peace promoted by José Trinidad Muñoz, and mediation offered by the president of El Salvador, Estrada continued the war, losing to William Walker.

Estrada fled the country soon after, returning to reorganize a Legitimist government in Somotillo on 21 June 1856.

He appointed Tomás Martínez as the Commander in Chief of the military, who would eventually become President after Walker was driven out of the country.
