The group will be performing alongside the likes of Colombian starlet Shakira.
"Evento 40" organizers said they are expecting an audience of over 50,000 at the festival.
There will be 15 acts performing at the two-day event and it will be broadcast throughout South America through Colombia's private broadcaster CaracolTV Principales.
The seven-member Korean boy band said it was thrilled to be invited to the event as a "K-pop representative."
"We heard that K-pop is sweeping across South America at the moment," the band said in a statement. "It's also our first time visiting Colombia and as representatives of K-pop and Asian artists, we will try our best to infect the nation with K-pop fever."
