The Slovakian has been in fine form this season, scoring seven goals to lift Napoli into the thick of the title battle in Italy.
And the 25-year-old insists he has no plans to walk away from the Serie A side any time soon.
"I've been here for several years. I'm growing together with Napoli," said Hamsik.
"Napoli are becoming a big club and I'm happy to be part of this team. I have a contract until 2016."
Asked about the prospect of star forward Edinson Cavani leaving Naples, Hamsik added: "He extended his contract for five years a while ago. I hope and think he'll stay here for many years."
A more immediate concern for Napoli boss Walter Mazzarri will be the fitness of Christian Maggio after the wing-back suffered a fractured hand in training on Friday.
The Italy international will miss Sunday's trip to Parma after undergoing surgery on the problem.
