Boletus subalpinus, commonly known as the gasteroid king bolete, is a species of fungus in the family Boletaceae. The species was first described scientifically in 1969 by American mycologists Harry Delbert Thiers and James M. Trappe. It was originally named as a species of Gastroboletus but was found to be in Boletus sensu stricto in a 2013 molecular phylogenetics study.
The cap is 5–12 centimetres (2–4+3⁄4 in) wide, buff, convex and then flattening. The flesh is whitish, staining bluish or sometimes pink. The pores are pale then darken and produce no spore print. The stalk is up to 6 cm long and 5 cm thick, pale and darkening with age, sometimes darker at the base.
The species is found in California and Oregon.
