Astragalus williamsii is native to southern Alaska and Canada's Yukon territory. It is found in forests, grasslands, and inland wetlands, at elevations from 600–1,800 metres (2,000–5,900 ft). The species grows in sand or gravel near the banks of creeks, and near aspen trees in open woodlands. It has been found growing in podzol. The type specimen was collected near the Big Salmon River in 1899. The species was described in 1900.
