The 24-year-old winger, who can also play centre, says that he is “pleased” to be staying with the club.
“I’m very pleased to have agreed a new deal and I’m looking forward to another couple of years at the Jungle,” said Dixon.
“I’ve really enjoyed my time at the club after gaining promotion in my first year we have built over the last two years and are moving forward.
“I’m confident that we are heading in the right direction and I’m looking forward to being part of a club who are competing for trophies in the next few years.”
Dixon had played in every game this season before last weekend’s game with Bradford and could see himself rack up his 500th career point against former club Hull this weekend.
“I’m pretty happy with my own form and was disappointed to lose my ever present record last week – but I’m hoping to be back at the weekend against my old club Hull,” added Dixon.
Meanwhile, coach Terry Matterson added: “Kirk has been with us three years and he has improved in each of those years, and we feel that there is more to come from him.
“He covers two positions for us and a well as being a competent kicker he is proving a good finisher. He is also a popular member of the squad and I’m pleased that he has agreed a new deal with us.”
