Spyridium daltonii is a species of flowering plant in the family Rhamnaceae and is endemic to Victoria in Australia.

It is a shrub with softly-hairy branchlets, linear to narrowly elliptic leaves, and small groups of hairy, yellowish flowers.

Flowering occurs from August to October and the fruit is a capsule about 3 mm (0.12 in) long.

[2] This spyridium was first formally described in 1875 by Ferdinand von Mueller who gave it the name Trymalium daltonii in Fragmenta Phytographiae Australiae from specimens collected by St. Ely D'Alton.

[5][6] Spyridium daltonii grows in heathy woodland and is endemic to central areas of the Grampians in Victoria.
