The Explorer's Grand Slam, also known as the Adventurer's Grand Slam, is an adventurer goal to reach the North Pole and South Pole, as well as climb the Seven Summits: Everest, Aconcagua, Denali, Kilimanjaro, Elbrus, Vinson, and Puncak Jaya or Kosciuszko. The reason for a choice of Puncak Jaya or Kosciuszko was to give Explorer's Grand Slam participants a choice in following the Bass List (Kosciuszko) or the Messner List (Puncak Jaya) when choosing their seventh summit; for more information see paragraph entitled Controversy in Eight Summits.

Heo Young-Ho, a South Korean Alpinist, was the first person to complete the Explorer's Grand Slam, after he reached the South Pole from Berkner Island in January 1997. British Explorer, David Hempleman-Adams, unaware of Heo Young-Ho's achievements, claimed he was the first person, but this has proven to be incorrect. The top three to complete the Explorer's Grand Slam are: first, Heo Young-Ho, South Korean Alpinist, finishing with the South Pole in January 1997, second, Russian Survivalist Fyodor Konyukhov finishing with Denali in May 1997, and third, David Hempleman-Adams finishing with the geographic North Pole in 1998.
