They include experienced defensive quintet Ryan McGowan, Adam Chicksen, Nathaniel Knight-Percival, Paul Caddis and Calum Woods, alongside forward duo Billy Clarke and Alex Jones.
Knight-Pervical was a regular for most of last season and made 35 league appearances for the Bantams, including 34 starts.
Chicksen made 26 league starts at left-back, with Australian defender McGowan making 23 league appearances.
Knight-Percival, Clarke and Jones were the last links with the Bantams squad that reached the League One play-off final just under two years ago.
Meanwhile, Danny Devine, Luca Colville and Jermaine Anderson have been offered new deals, while Tyrell Robinson remains suspended while legal proceedings continue following his arrest last year.
Bradford-born Devine, 21, has been rewarded for impressing manager Gary Bowyer towards the end of the season following his return from injury, with ex-Peterborough United player Anderson, 22 – who joined on a short-term deal in January after an unsuccessful loan spell at Doncaster Rovers – also doing enough to be tabled fresh terms.
Youngsters Ben Wilson, Cameron Hawkes, Callum Gunnar and Tom Clare have also been released, with loanees Paudie O’Connor, Jack Payne, Jacob Butterfield, George Miller, Lewis O’Brien and David Ball returning to their parent clubs.
