The 15th World Scout Jamboree (Persian: پانزدهمین گردهمایی جهانی پیشاهنگان) was scheduled to be held 15–23 July 1979 and was to be hosted by Iran at Nishapur, but was cancelled due to the Iranian Revolution which took place in 1979.

[1] The 15th World Jamboree was to be held at the 10 square kilometres (3.9 sq mi) "Omar Khayyám Scout Park" [2] in the city of Nishapur.

[3] However, the destabilizing events of the Islamic Revolution caused the 15th World Jamboree to be cancelled near the end of 1978.

[4] However, a number of commemorative items had already been made for the event, the demand for which and the value of which was greatly inflated by the Jamboree's cancellation.

The few items of memorabilia in existence are of huge value to collectors when they, albeit rarely, come on the market.
