History
Mazapil's name derives from the Nahuatl place name Mazatlpilli, itself derived from mazatl "deer" and pilli "small".

The original inhabitants of the Mazapil valley were nomadic Chichimeca peoples known to the Spaniards as Guachichiles. Francisco de Ibarra reached the area in 1554. In 1562, Pedro de Ahumada y Samano reported finding the valley inhabited by 6000 native warriors armed with bows and arrows. Silver mines were first established in the valley in the late 1560s.

Mazapil was one of Zacatecas's eleven original subdivisions (then known as partidos) when the state's constitution was enacted in 1825. In 1885 the fall of a meteorite in the area during the Andromedids meteor shower attracted scientific attention, although a cometary origin for the meteorite is now considered unlikely and the timing of its fall has been ascribed to coincidence. 

In 1907 Gustavo A. Madero set up four factories in the municipality for the extraction of guayule rubber. Guayule from the Mazapil region was also exported to the US for rubber production during World War II.

Administration
Mazapil's municipal government comprises a president, secretary, councillor (Spanish: síndico), and six trustees (regidores). The current president of the municipality is Gregorio Macías Zúñiga.
