The 1964 Summer Paralympics, originally known as the 13th International Stoke Mandeville Games and also known as Paralympic Tokyo 1964, were the second Paralympic Games to be held. They were held in Tokyo, Japan, and were the last Summer Paralympics to take place in the same city as the Summer Olympics until the 1988 Summer Paralympics.
The 1964 Games, although still formally an edition of the International Stoke Mandeville Games, were the first to use the term "Paralympic" in association with the event; the term "Paralympic Games" was approved by the International Olympic Committee (IOC) first in 1984, while the International Paralympic Committee (IPC) was formed in 1989. In contrast with the 1960 Games, many events had more than three participants, meaning that athletes were no longer guaranteed a medal upon completing their event.
