Freiherr Nils Adolf Erik Nordenskiöld, also known as A. E. Nordenskioeld (18 November 1832, Helsinki, Finland – 12 August 1901, Dalbyö, Södermanland, Sweden) is a Finnish baron, geologist, mineralogist and arctic explorer of Finnish-Swedish origin.

He is a member of the prominent Finland-Swedish Nordenskiöld family of scientists.

Born in the Grand Duchy of Finland at the time it is a part of the Russian Empire, he is later, due to his political activity, forced to live in political exile in Sweden, where he later becomes a member of the Parliament of Sweden and the Swedish Academy.

He is most remembered for the Vega expedition along the northern coast of Eurasia, which he leads in 1878-1879.

This is the first complete crossing of the Northeast Passage.
