Basque Pelota was a demonstration sport at the 1968 Summer Olympics in Mexico City.
It was the third time that the sport was included in the Olympic program; it was an official Olympic sport at the 1900 Games in Paris, and a demonstration sport in 1924.
It would be included as a demonstration sport once again at the 1992 Games in Barcelona.
[1] Note: Since Basque Pelota was a demonstration sport, medals were awarded, but the medals were not "official" (and did not count in the respective nations' medal totals).
