GLAM (short for Girls be Ambitious) was a South Korean girl group under Big Hit Entertainment & Source Music. They debuted with the single "Party (XXO)" in July 2012. GLAM originally consisted of five people, but one of the original members, Trinity, left the group in late 2012.

In January 2015, Dahee was found guilty of blackmailing actor Lee Byung-hun and was sentenced to one year in prison, but was released early at the request of Lee. GLAM disbanded shortly after.
