National Hispanic Heritage Month will be observed from September 15 to October 15, 2026. The period marks the celebration of the heritage, history, traditions, and cultural diversity of Hispanic Americans whose heritage is rooted in Spain and 19 countries and territories: Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Ecuador, Peru, Bolivia, Paraguay, Chile, Argentina, Uruguay, Cuba, Puerto Rico, and the Dominican Republic. The national observance began in 1968 as Hispanic Heritage Week under President Lyndon Johnson and was expanded by President Ronald Reagan in 1988 to cover 30 days starting September 15 and ending October 15 of each year. It was enacted into law on August 17, 1988.
National Hispanic Heritage Month is observed and celebrated to highlight the independence of several countries. September 15 is the day that five Latin American countries celebrate their independence from Spain: Costa Rica, El Salvador, Nicaragua, Guatemala, and Honduras. Mexico celebrates its independence on September 16 and Chile on September 18. Also, Indigenous Peoples Day, or Día de la Raza, in mid-October, falls within these 30 days.
