Nils Strindberg (4 September 1872 – October 1897) was a Swedish photographer and scientist.

He was one of the three members of S. A. Andrée's ill-fated Arctic balloon expedition of 1897.
Strindberg was invited to the Arctic balloon expedition of 1897 to create a photographic aerial record of the arctic.

the group ended up exhausted on the deserted Kvitøya (White Island) in Svalbard and died there. For 33 years the fate of the expedition remained one of the unsolved riddles of the Arctic.

When the remains of the expedition were discovered by the Bratvaag Expedition in 1930 Strindberg's body and those of the other two explorers were brought back to Sweden for a funeral with great honors. 

After cremation, their ashes were interred together at the cemetery Norra begravningsplatsen in Stockholm.
