Jonas Björler (born 26 February 1973) is the bass player of the melodic death metal bands, At the Gates and The Haunted. He was formerly in the bands Demolition, Infestation and Terror. He is also a qualified accountant.

Björler was the original drummer of the band due to being the drummer of the previous band Infestation, but it was soon discovered that he wasn't able to drum for the band and became their bassist instead. Along with Tomas Lindberg, he is one of the original members left in the band.

Formed after the split-up of At the Gates in 1996. Jonas is a founding member together with Patrik Jensen and Adrian Erlandsson.
