Juanacatlán (Spanish pronunciation: [xwanakaˈtlan]) is a town and municipio (municipality) in the central region of the Mexican state of Jalisco.

[3] The hieroglyph of Juanacatlán includes the symbol of the Tlaxcala, representing the battles and the places where the Tlaxcaltecans went with the Nuño de Guzmán expedition, after the conquest of Mexico.

The region's hydrography includes the Santiago River, which surrounds much of the town, and the streams that flow in the rainy season: the Colorado, Buenavista Los Corteses, La Cruz, la Tinaja, El Gallo, El Puerto, Hondo, Miseria, Chiquito, Lomelines, and Limoncillo.

Since companies appearing in the industrial corridor of El Salto have polluted the waters, the waterfall that once attracted hundreds of visitors is now a hotbed of infection, with a terrible odor, worse in times of heat.

There are also minor species such as: guamúchil, bell, captain, tepamé, mesquite, nopal, huizache, and a variety of fruit trees.

Fishing in the Rio Santiago produces species such as catfish, lobina, carp and frog on a small scale for local consumption.

The Juanacatlán Lagoon offers a landscape worthy of admiration, for the transparency of its water and vegetation, with a surrounding forest of conifers.
