Indigenous peoples of Mexico (Spanish: pueblos indigenas de Mexico), Native Mexicans (Spanish: nativos mexicanos), or Mexican Native Americans (Spanish: nativo america mexicanos), are those who are part of communities that trace their roots back to populations and communities that existed in what is now Mexico prior to the arrival of Europeans. According to the National Commission for the Development of Indigenous Peoples (Comision Nacional para el Desarrollo de los Pueblos Indigenas, or CDI in Spanish) and the INEGI (official census institute), in 2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population.

Generally, indigenous Mexicans live more poorly than non-indigenous Mexicans however, social development varies between states, different indigenous ethnicities and between rural and urban areas. In all states indigenous people have higher infant mortality, in some states almost double of the non-indigenous populations.  Some indigenous groups, particularly the Yucatec Maya in the Yucatan peninsula and some of the Nahua and Otomi peoples in central states have maintained higher levels of development while indigenous peoples in states such as the Guerrero or Michoacan are ranked drastically lower than the average Mexican citizen in these fields. Despite certain indigenous groups such as the Maya or Nahua retaining high levels of development, the general indigenous population lives at a lower level of development than the general population.  Literacy rates are much lower for the indigenous, particularly in the southwestern states of Guerrero and Oaxaca due lack of access to education and a lack of the educational literature available in indigenous languages. Literacy rates are also much lower, with 27% of indigenous children between 6 and 14 being illiterate compared to a national average of 12%. The Mexican government is obligated to provide education in indigenous languages, but many times fails to provide schooling in languages other than Spanish. As a result, many indigenous groups have resorted to creating their own small community educational institutions.  The indigenous population participate in the workforce longer than the national average, starting earlier and continuing longer. A major reason for this is that significant number of the indigenous practice economically under productive agriculture and receive no regular salaries. Indigenous people also have less access to health care.
