Tiny Dynamine is an EP by Scottish alternative rock band Cocteau Twins, released on 4AD Records.

The EP was later included in its entirety on the 1991 compilation The Box Set and the 2005 singles/EP collection Lullabies to Violaine.

The tracks on Tiny Dynamine and Echoes in a Shallow Bay were initially recorded to test the production capacities of a new studio.

When the band decided the material was strong enough for release, they completed the recording process and issued the finished product on two EPs.

Most are obscure, but the dynamine is a genus of nymphalid butterflies found in South America, the plain tiger is a common Asian butterfly and the lyrics to "Melonella" (on Echoes In A Shallow Bay) are simply a recounting of various Lepidopteric family names such as Hesperiidae and Papilionidae.
