Schacontia themis is a moth of the family Crambidae described by Maria Alma Solis and Paul Z. Goldstein in 2013.

It is found on the Cayman Islands and in Brazil, Costa Rica, Cuba, the Dominican Republic, Florida, Jamaica, Mexico, Panama, Puerto Rico and Venezuela.

The ground colour of the forewings is straw, with few contrasting markings other than jagged chocolate-brown antemedial and postmedial lines.

The hindwings are almost uniformly pale, shaded brown at the subterminal area.

The specific epithet refers to Themis, the Greek Titaness and embodiment of divine order.
