Ben Kasica (born April 15, 1984) is the guitarist for the Christian rock band Skillet. He joined the band in 2001 at the age of sixteen, and has recorded the albums Alien Youth, Collide, and Comatose with them. He is the youngest member of the band by far, and while he didn't join the band until five years into its existence, he was only twelve when the band was first formed.

He began playing guitar at age eleven, beginning with a more classical style, but he switched to playing electric guitar about two years later. However, his classical influence can be seen in many of his solos, most notably the one on the song "Falling Inside the Black" on Comatose.

Kasica played GMP Guitars exclusively when he first joined the band. However, GMP has discontinued their line of guitars, and he and fellow Skillet guitarist Korey Cooper now use PRS Guitars. Kasica is known for his many tricks while playing the guitar live on stage. These range from his amazing solos to playing his guitar behind the back of his head.

In interviews and blogs, fellow Skillet guitarist Korey Cooper said that Ben is her "coffee friend", because they both have a love of coffee.

During shows, Ben often wanders around his side of the stage, and Lori Peters has said that he will do things such as make faces at her or rock out on the drum riser.

John Cooper said in the youtube interview that he enjoys having Ben in the band "for his integrity--he's[Ben's] someone who wants to be honest about things".
