The Polish international joined Die Roten from Lech Poznan in 2016, playing a key role in their promotion to the Bundesliga last term and has continued his form in the top flight.
Kaminski has made 16 appearances so far this term and after agreeing a new deal until the summer of 2021, says he is excited to be continuing his career at the Mercedes-Benz Arena.
"I am delighted that I will be continuing with VfB into the future,' he told the club's official website.
"Within the team and the club, as well as here in the city, I feel very much at home.
"The club's ambitious targets in the coming years very much tally with my own and I want to be a part of a successful future at VfB."
