Dutch international Hasselbaink, 34, was out of contract after new Middlesbrough manager Gareth Southgate told him he could leave the Riverside Stadium.

Hasselbaink also had talks with Celtic but the Scottish champions could not agree a wage package to lure him to Parkhead.

The ex-Chelsea player becomes Charlton boss Iain Dowie's second signing since he took charge at The Valley earlier this summer, following the capture of Leeds teenager Simon Walton.

Dowie told the club's website: "He brings leadership to the club. He is a leader generally around the place, in the dressing room and on the pitch.

"He's played internationally for Holland and his goal record is outstanding.

"He brings goals to the club and also an infectious enthusiasm, he is a bubbly character and always has a smile on his face."
