Chichicastenango, also known as Santo Tomás Chichicastenango, is a town in the El Quiché department of Guatemala, known for its traditional Maya Indian culture.

Chichicatenango is a small and stucco-white town, lying on the crests of mountaintops at an altitude of 1,965 meters. It is located about 140 km and 2-3 hours drive northwest of Guatemala City and is home to what is surely the most colorful native market in North and Central America, perhaps in all America.

The famous handicraft market of Chichicastenango draws not only the K'iche' Maya of the surrounding region, but vendors from all over Guatemala. They represent many of Guatemala's linguistic groups such as Mam, Ixil , Kaqchikel and others, each hawking his or her products in a riotous cacophony of color, dialects and costumes, smoke, and smells. This town in the mountains of El Quiché has been, since pre-Hispanic times, one of the largest trading centers in the Maya area.

Vendors begin setting up portable booths in the main plaza and adjacent streets of "Chichi" the night before and set-up continues in the early daylight hours. Outstanding among the items offered are textiles, particularly the women's blouses. The manufacture of masks, used by dancers in traditional dances has also made this city famous for woodcarving. Much of what is sold is of good quality, but there is also products in Chichi's many factories for the not-so-discerning foreign companies.

Another major attraction in Chichicastenango is the 400-year old church of Santo Tomas which is situated next to the market. It is built atop a Pre-Columbian platform, and the steps originally to a temple of the pre-Hispanic Maya civilization remain venerated. Shamans still use it for their rituals, burning incense and candles and in special cases a chicken for the gods. Each of the 18 stairs that lead up to the church stands for one month of the Maya calendar year. The Mayan calendar has 18 month of 20 days each.
