The 1968 Summer Olympics, officially known as the Games of the XIX Olympiad, were an international multi-sport event held in Mexico City, Mexico, in October 1968.

These were the first Olympic Games to be staged in Latin America and the first to be staged in a Spanish-speaking country. They were also the first Games to use an all-weather (smooth) track for track and field events instead of the traditional cinder track.

The 1968 Games were the third to be held in the last quarter of the year, after the 1956 Games in Melbourne and the 1964 Games in Tokyo. The Mexican Student Movement of 1968 happened concurrently and the Olympic Games were correlated to the government's repression.
