Boykinia richardsonii is a species of flowering plant in the family Saxifragaceae, endemic to Alaska and the adjacent Canadian territory of Yukon. It is commonly known as Richardson's brookfoam, but has also been called Alaska boykin, bearflower, Richardson's boykin and Richardson's saxifrage. "Bearflower" reflects its popularity with grizzly bears as forage in the summer months when it flowers.

The species is named for Scottish naturalist John Richardson, who first identified it on his mid-1820s exploration of the western Canadian Arctic coast with John Franklin. William Jackson Hooker first described it in Flora Boreali-Americana, the 1833 account of plant species identified on that expedition. It was originally misclassified as part of the genus Saxifraga.

Boykinia richardsonii is believed to have evolved in temperate Arctic forests of the Neogene, or Late Tertiary, period and survived through the ensuing glacial periods since much of Beringia remained an unglaciated refugium. Today it is found at lower elevations in open meadows or tundra, along streams, and sometimes in the shade provided by Arctic willow.
