CARLTON has secured the signature of one of its brightest young stars, with developing forward Charlie Curnow extending his contract until the end of 2023.

Curnow, who has established himself as one of the game's best young players, still had one year remaining on his current deal before extending for a further four seasons.

"I'm very thankful to the club for the opportunity to extend my contract for a further four years," Curnow said.

"It was never an option to go anywhere else, the club is basically an extension of my family and I wanted to repay the faith they have shown in me since I arrived at the end of 2015.

"I really believe in where our football program is heading. We are a very close-knit playing group and we are driven to get this club back to where it belongs so I’m rapt to be staying around and helping us get there." 

A prodigious junior prospect, Curnow joined his older brother Ed at the Blues when he was recruited to the club with pick No.12 in the 2015 NAB AFL Draft.

The 21-year-old enjoyed a breakout season last year, impressing with his marking ability and his athleticism, booting a total of 41 goals throughout his first 37 AFL matches.

Curnow's four-year deal is likely to followed by an extension for fellow young star Patrick Cripps, who is also set to re-sign with the Blues in the coming months.

Young midfielders Paddy Dow, Zac Fisher and Lochie O'Brien have also penned contract extensions with Carlton over the course of the season.
