Aureoboletus auriporus, is a species of bolete fungus in the family Boletaceae that is found in Europe and North America. It was originally described in 1872 by American mycologist Charles Horton Peck, who called it Boletus auriporus. Zdenek Pouzar transferred it to the genus Aureoboletus in 1957.

The species is edible, and could be confused with (the also edible) Xerocomus illudens.
