Novius is a genus of ladybird beetles belonging to the family Coccinellidae, and the sole member of the tribe Noviini.

[1] Novius species have a semispherical body, covered with dense, short hairs.

Novius species regularly feed on scale insects, aphids and small mites, which makes them candidates as biological control agents.

One such species used in biocontrol is Novius cardinalis, introduced worldwide in tropical and subtropical regions, and now effectively cosmopolitan.

Other species have been introduced in more restricted areas (e.g., Micronesia), though always for the biological control of pest insects.
