Solidago rigida, also known by the common names stiff goldenrod and stiff-leaved goldenrod is a North American plant species in the Goldenrod family. It is native to the region between the Atlantic Coast and the Rockies, from Alberta east to Ontario, south as far as New Mexico, Texas, and Georgia. In New England, it grows today only in Connecticut, though there are historical records indicating that it formerly grew in Rhode Island and Massachusetts.
