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.
