Manuel María Eutimio de Zamacona y Murphy (13 September 1826 – 29 May 1904) was a Mexican radical liberal lawyer, journalist, and politician.
Born in Puebla, he studied at seminary and went on to practice law.
[5] He served as minister of Foreign Affairs in the cabinet of President Benito Juárez (1861).
[1][6] He negotiated an agreement with the British Ambassador to Mexico, Charles Wyke, known as the Wyke-Zamacona Treaty, which sought an interim solution of the Juárez government's problems concerning the external debt to Great Britain, France, and Spain.
The treaty was aimed at forestalling that, but it was rejected by the Mexican congress.
