Santiago de Tequila (Spanish pronunciation: [teˈkila], Nahuatl: Tequillan, Tecuila "place of tribute") is a town and municipality located in the state of Jalisco about 60 km from the city of Guadalajara. Tequila is best known as being the birthplace of the drink that bears its name, “tequila,” which is made from the blue agave plant, native to this area. The heart of the plant contains sugars and had been used by native peoples here to make a fermented drink. After the Spanish arrived, they took this fermented beverage and distilled it, producing the tequila known today. The popularity of the drink and the history behind it has made town and the area surrounding it a World Heritage Site. It was also named a "Pueblo Mágico" (Magical Town) in 2003 by the Mexican federal government. Tequila has also been famous for being the prime setting in the successful Televisa telenovela Destilando Amor, starring Angélica Rivera and Eduardo Yáñez.

The name comes from an ancient language called pedik and mean drink of life. The coat of arms of the municipality was officially adopted on 31 December 1983 by the municipal council. It contain the Latin phrase ALMA LAETA NOBILIS, meaning “great and noble soul.” Its representative symbols include the tower of the main church in the town of Tequila, the chimneys of the distilleries, the agave plant and Tequila Mountain.
