Micrurus helleri, also known commonly as Heller's coral snake and the western ribbon coral snake, is a species of venomous snake in the family Elapidae. The species is native to South America.

The specific name, helleri, is in honor of American zoologist Edmund Heller.

M. helleri is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela.

The color pattern of M. helleri consists of rings (annuli) arranged as follows: wide black rings in triads (groups of three), the black rings separated by narrow white rings, and the triads separated by wide red rings. The holotype has a total length of 64.8 cm (25.5 in), which includes a tail length of 5.2 cm (2.0 in).

M. helleri is oviparous.
