Butyriboletus peckii is a fungus of the genus Butyriboletus native to eastern North America.

It was first described by Charles Christopher Frost in 1878.

Recent changes[3][4] in the phylogenetic framework of the Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus.

[5] In 2015, Kuan Zhao and colleagues published analysis that demonstrated that the bolete belongs to Butyriboletus, closely related to Butyriboletus pulchriceps.
