The former York player has signed a four-year deal with the club, and a transfer fee of £140,000 was paid by Warrington to Hull for his services.
“We are delighted to have captured the services of such an outstanding talent,” Wolves head of coaching and rugby Tony Smith said.
“we are always keen to recruit elite, young British players. Tom’s try-scoring speaks for itself and he is a player I have greatly admired for years since he came on the scene.
“His size and speed are also greatly suited to the wing position in Rugby League. I look forward to working with him next year and we hope he continues his good form.
“I have no doubt he will be a representative player in the near future. He was keen to join our club and we will look forward to welcoming him when the time comes.”
Lineham himself is looking forward to playing for one of Super League‘s top sides.
“Warrington is a good club with some great players, coaches and a strong fan base,” he said.
“It is very similar to Hull FC in many ways and I’m looking forward to being part of that.
“The circumstances are right for me to make the move so I’ll be looking forward to finishing the season on a high at Hull and hit the ground running when I join up with my new team mates for pre-season.
“It is a new chapter in my life and I am looking forward to seeing where that takes me with Warrington over the coming years as they’re a club that will always be in and around the top of the league challenging for honours.”
