Winger Matty Phillips is departing West Bromwich Albion after eight years.
Adam Reach, Nathaniel Chalobah, Erik Pieters, Yann M’Vila, Martin Kelly and Jovan Malcolm will also be leaving the club.
New contracts have been offered to defenders Cedric Kipre and Kyle Bartley as well as midfielder Alex Mowatt.
Phillips was signed by then boss Tony Pulis from QPR in July 2016 and the 33-year-old scored 31 goals in his 255 appearances for the club in all competitions.
He played an influential part in the club's promotion to the Premier League in 2020 but has made less of an impact under head coach Carlos Corberan, last scoring against Hull City in November.
