Gerhardus Marinus Maria "Gerard" Nijboer (born 18 August 1955) is a former Dutch long-distance runner. Nijboer competed in three consecutive Summer Olympics, starting in 1980 (Moscow, Soviet Union), when he won the silver medal in the marathon. He became European champion in the marathon in 1982, for which he was named Dutch Sportsman of the year.
- The International Association of Athletics Federations has published a progression of road racing world bests and records that were widely recognized prior to ratification and official acceptance by the IAAF. According to that progression, Clayton's 2:08:34 performance in Antwerp on May 30, 1969 was a world best at the time. Other road racing authorities, including the Association of Road Racing Statisticians, consider Clayton's performance to have occurred on a short course and recognize other athletes - including Nijboer - in the progression for world best in the marathon.
