Reports had suggested that the 30-year-old Napoli midfielder was prepared to join the Blues at the end of the campaign.
However, representative Massimo Briaschi is adamant that Maggio will see out his contract in Naples.
"Chelsea interested in Maggio? There is no news there," Briaschi told tuttomercatoweb.com.
"Christian extended his contract at Napoli until 2017 and that says it all. There is, and there won't be, any news on this.
"It is clear that Christian wants to stay here, maybe until the end of his career. If he didn't, he would have tried to run down his contract with Napoli."
Maggio joined Napoli in in 2008 from Sampdoria.
