The Frenchman has finally signed for the Magpies after the club were long-linked with the 24-year-old.
Cabella arrives at St James' Park for an undisclosed fee, with his six-year deal suggesting Alan Pardew plans to make him an integral part of the Newcastle side.
And the France international says he is delighted to finally be on Tyneside, promising to give his 'maximum' for the club.
"It is great to finally be a Newcastle player," he told the club's official website.
"This is a move that I really wanted to make, as I have heard nothing but good things about Newcastle United from everyone I spoke to.
"I wanted to join a great English club and that is why I have arrived here. I'm looking forward to pulling on the shirt and playing in this magnificent stadium, and I will give this Club my maximum."
Meanwhile, Magpies boss Pardew said: "Remy is a player who has been on our radar for a while and we are delighted to bring him to the Club.
"He is a player who I am sure will excite our fans. He has flair, hard work and commitment, and is going to bring a talent, energy and quality to St. James' Park that our supporters will enjoy.
"Remy has great ideas when the ball comes to him, and along with Siem de Jong is going to improve an area where we definitely needed some help."
