Juncos was founded on the request of Tomás Pizarro on August 2, 1797, having previously been a village which evolved from a small ranch, the Hatillo de los Juncos. This ranch was part of the Hato del Valenciano, which gave its name to the Río Valenciano which bisects the city before joining the Río Gurabo to the north of the settlement.


During the 17th century, large parts of the municipality were owned by the Hato Grande de los Delgado (The Delgados' Great Ranch). Another ranch, the Hato del Valenciano (Valencian's Ranch), was established and later divided into the Hatillo de los Lirios (Small Ranch of the Lilies) and the Hatillo de los Juncos (Small Ranch of the Reeds). This second one became the village of Juncos in the 18th century and was given the status of a town on August 2, 1797. Reeds, which gave the city its name, feature in the center of its flag and the bottom of its coat of arms. The Hato del Valenciano is remembered in the name of the Río Valenciano, as well as the coat of arms of Valencia featuring in Juncos' coat of arms, in addition to the city's two nicknames of La Ciudad del Valenciano (The Valencian's City) and Los Mulos del Valenciano (The Valencian's Mules).[2]


On the flag of Juncos, on a gold field, blue waving stripes cross horizontally in the lower half. These represent the Río Valenciano which bisects the city. Green reeds with red buds appear in a central point above the stripes, representing the city's name (Juncos is Spanish for reeds).

Juncos' coat of arms is divided into four quarters, with the upper left and lower right containing vertical stripes gold (or yellow) and gules (red) in reference to the Spanish region of Valencia and to its denomination as "Town of Valencia". The upper right quarter is blue with twelve silver stars to represent the Virgin Mary, and also features a cross confirming the city as part of Christendom. The lower right is split vertically between an image of a tobacco plant to represent the city's agriculture and a chimney to represent industrialization and sugar cane processing. Like the flag, a waving blue line representing the Río Valenciano crosses the shield horizontally.

The shield is topped with a civic crown [3] in the shape of a three-towered castle. Underneath the shield lie the red-budded green reeds which gave the city its name, which features alongside its year of foundation (1797) at the very bottom.[4]


Juncos[5] is in the central eastern part of the island.

Hurricane MariaEdit

Hurricane Maria on September 20, 2017 triggered numerous landslides in Juncos with the significant amount of rainfall.[6][7]


Subdivisions of Juncos.

Like all municipalities of Puerto Rico, Juncos is subdivided into barrios. The municipal buildings, central square and large Catholic church are located near the center of the municipality, in a barrio referred to as "el pueblo".[8][9][10][11]

Under the administration of Alfredo "Papo" Alejandro, Juncos started a collective ferry-on-wheels transportation system.

Special communitiesEdit

Since 2001, when law 1-2001 was passed,[18] measures have been taken to identify and address the high levels of poverty and lack of resources and opportunities affecting people living in specific places (barrios, communities, sectors, or neighborhoods) of Puerto Rico. In 2004, the following places in Juncos were on the list of Comunidades especiales de Puerto Rico or marginalized communities:[19]

  • Flores
  • Santana 1 in Ceiba Norte
  • Canta Gallo
  • El Caracol
  • La Cuesta, Sector El Mangó
  • La Hormiga
  • Lirios Dorados, Hoyo Hondo
  • Rosalía, Sector El Mangó

In 2017, Governor Rosello created a new government agency to work with the Special Communities of Puerto Rico Program and Jesús Vélez Vargas, its director stated that the program was evolving.[20][21]

In 2009, Juncos became the home of the 2008 Puerto Rico Soccer League champions, Sevilla Bayamon FC. The club is now known as Sevilla-FC Juncos since being relocated to the city. The team moved to Juncos due to ownership and financial problems and currently play in the Alfredo "Papo" Alejandro Stadium.
