Electronicore (not to be confused with Trancecore) is a genre of music combining metalcore or post-hardcore with electronic music. It is often used interchangeably with Trancecore, however these are different genres with different styles. Chiptune combined with post-hardcore and metalcore is called nintendocore, which may or may not be considered separate from electronicore.

Although it is a portmanteau of "trance" and "hardcore", trancecore was coined to term post-hardcore and metalcore artists that infuse synthesizers in their breakdowns and use autotuned vocals in their choruses. Electronic combined with hardcore punk is sometimes called digital hardcore but also sometimes is put under electronicore due to digital hardcore's association with noise and industrial. Electronic combined with grindcore is called cybergrind or electrogrind.

Popular electronicore acts are Asking Alexandria, Attack Attack!, The Browning, Crown the Empire, Enter Shikari, Fear, and Loathing in Las Vegas, I See Stars, Strawberry Hospital, and We Came as Romans.
