Puebla is one of the thirty-one states comprising the Federal Entities of Mexico, officially designated as the Free and Sovereign State of Puebla. Located in east-central Mexico within the central highlands between the Sierra Nevada and the Sierra Madre Oriental, it occupies a triangular area of 33,919 square kilometers. The state is bordered by Veracruz to the north and east, Hidalgo, México, Tlaxcala, and Morelos to the west, and Guerrero and Oaxaca to the south. Its capital city shares the name Puebla and serves as the administrative center for the region's 217 municipalities.

The origins of the state lie in the city of Puebla, which was founded by the Spanish in 1531 to secure the trade route between Mexico City and the port of Veracruz. By the end of the 18th century, the area had become a colonial province with its own governor before becoming the State of Puebla following the Mexican War of Independence in the early 19th century. The city was listed as a UNESCO World Heritage Site due to its architecture, recognized as the cradle of Mexican Baroque and one of the five most important colonial cities in Mexico.

The state features diverse geography including the Huasteco Plateau, volcanic peaks like Pico de Orizaba, and numerous river systems emptying into the Pacific Ocean and the Gulf of Mexico. The capital city is surrounded by volcanoes and snow-capped mountains, slightly over 110 kilometers southeast of Mexico City. Its historic center contains over 5,000 buildings in Baroque, Renaissance, and Classic styles, constructed from gray cantera stone, red brick, and multicolored tiles, defining its status as a major colonial heritage site.

Puebla is home to five major indigenous groups: Nahuas, Totonacs, Mixtecs, Popolocas, and Otomi. The region is famous for the china poblana, mole poblano, and festivals such as Cinco de Mayo, which commemorates the 1862 defeat of a French expeditionary army. Other cultural events include the Ritual of Quetzalcoatl, Day of the Dead celebrations in Huaquechula, and Carnival in Huejotzingo. The city is also renowned for its cuisine, particularly the invention of mole, a famous Mexican spicy thick sauce.

The state has a population of 6,168,883 as of 2015, while the capital city had 1.7 million inhabitants in 2020. It is one of the most industrialized states in Mexico, though development is concentrated in urban areas, leaving many rural regions undeveloped. The climate varies by altitude with an average temperature of 16 °C and a rainy season from May to October. Access is facilitated by continual bus services from Mexico City and ridesharing options, with travel times and costs varying by service provider.
