Minichiello first joined the Roosters in 1997 and made his first grade debut for the tricolours in 2000.
The representative full-back has played 251 games for the club and will be replacing Braith Anasta after the lock joined the Wests Tigers after the 2012 season.
The 2005 Golden Boot winner said he was so proud to be named the skipper of the club that he loves and has spent so much time playing for.
“The Roosters are a club renowned for their tradition and history, and to look at names like Fittler, Messenger and Beetson, to join that list is an incredible honour,” Minichiello said.
“There’s a great young talented squad here and the club has a bright future. To have the chance to lead us in our premiership campaign is a role I’m ready for and will never take for granted. This is definitely one of the biggest highlights of my career so far.”
The Roosters also announced the appointment of Mitchell Pearce, Jake Friend, Jared Waerea-Hargreaves and Boyd Cordner as vice captains.
New Roosters Head Coach, Trent Robinson, said that Minichiello was a perfect leader for the club and will bring a great deal of experience to the role.
“Anthony is to be commended for his attitude to life and to training. He trains hard and is respected by the players,” Robinson said.
“Mini goes above and beyond the call of duty, leads by example and his attitude rubs off on the younger players. He typifies what we want to be as a football club and where we are headed.
“There are a number of players in the team who lead – whether it by their leadership on field, at training or away from the footy field, and in appointing four vice captains, we are recognising members of our senior group identified for their natural leadership while looking ahead to their future and nurturing their development.
“Captaincy can be a demanding role, and while Anthony will lead from the front, having more than one leader is an advantage for the club as a whole.
“Mitchell, Jake, Jared and Boyd are leaders in their own right and will act in supporting roles to Mini on and off the field.
“In today’s game, our players are competing at such a young age and it is important that we have leaders who are respected for the way they conduct themselves in all facets of club life.”
