John Graham (born June 18, 1956) is a former long-distance runner from Scotland, who won the inaugural Rotterdam Marathon on May 23, 1981 in a time of 2:09:28. He twice finished in fourth place in the men's marathon at the Commonwealth Games (1982 and 1986).

The Huntly Half Marathon in New Zealand began in 1981, established by a group of Huntly joggers who wanted to create a unique road race over the half-marathon distance. That inaugural race attracted 150 participants and was won by Graham with Alison Roe taking the women's race.
