Nuevo Progreso (Spanish pronunciation: [ˈnweβo pɾoˈɣɾeso]) is a municipality in the San Marcos department of Guatemala.

After the murder of president general José María Reina Barrios on 8 February 1898, lawyer Manuel Estrada Cabrera reached power and from the very beginning of his tenure he set up a dictatorial rule, which would last 22 years.

[2] [3] The president admirers began a program by which numerous locations and structures were named after the Presidente, and then El Progreso became "Estrada Cabrera" in 1898.

In 1908, following with the adulation program, the municipality was renamed, this time as "San Joaquin", a male version of Estrada Cabrera's mother name, Joaquina Cabrera -who had died on 3 July 1908- during the Fiestas Minervalias on 4 November 1908.

[4] Nuevo Progreso is also known as "El Valle Escondido" (English: "The hidden valley") of the San Marcos Department coast.
