The Tokyo International Marathon was a marathon for male elite runners held in Tokyo, Japan, from 1980 until 2006.

It actually consisted of two marathons - the Tokyo International Marathon which took place on even years, and Tokyo-New York Friendship International Marathon which took place on odd years. In the inaugural year, 1981, both marathons took place. However, because it was not possible to support two marathons a month apart in the same city, from 1982, the alternating format went into effect. The events were replaced in 2007 by the Tokyo Marathon, a race which is open to general runners of both sexes.

Between 1979 and 2008 there was also a Tokyo International Women's Marathon for female elite runners in November.
