Oxytropis splendens, commonly known as showy locoweed, is a flowering perennial in the legume family endemic to the east slope of the Rocky Mountains.

When in bloom, it grows dense spikes of rich lavender flowers, rising from among pinnately compound basal leaves.

Alaska, Yukon, District of Mackenzie, to Lake Superior, south to southeastern British Columbia, New Mexico, North Dakota, northern Minnesota, and Colorado.

It favors grassy slopes, open woods, clearings, gravelly river flats, banks, and roadsides.

Its nitrogen fixing properties and quick colonizing of poor soils make it a favorable plant for revegetation.
