The 28-year-old has made nearly 250 appearances for the side after joining from Featherstone Rovers nearly 10 years ago.
Whiting's new terms at the KC Stadium are due to expire in 2016.
"This is my club, it's my home and I am very proud to represent Hull FC," he is quoted as saying by Sky Sports News. "I have had a great 10 years with the club, but I am just as excited about the future now as I was when I joined in 2004."
Whiting has scored 71 tries during his time at Hull.
