Ole Nilsen Ravna (31 October 1841 - 11 August 1906) was a Northern Saami adventurer, explorer and reindeer herder.

Ole Nilsen Ravna was born on October 31, 1841, in Karasjok Municipality in Finnmark county, Norway.

The head of expedition, Fridtjof Nansen, was displeased with him, because Ravna had a family and motion sickness.

For the last reason, Ole and his compatriot Samuel Balto had been reading the New Testament during storms.

In 1905, the sixty-four-year-old Ole Ravna went with his compatriot Isak Klemetsen and Knud Rasmussen to the Greenland again.
