The 36-year-old's current deal had been due to expire at the end of the current season but after lengthy discussions with the capital club the Giallorossi legend revealed his delight at extending his stay with his hometown club on Friday.
"I have another two years of responsibilities and I'm sure we'll achieve some great things together," Totti told reporters at a press conference.
"I'd like to thank the president for this new contract. Everyone wanted it to happen, me and the club."
Totti made his Roma debut back in 1992 and has gone on to win Serie A, the Supercoppa Italiana twice and the Coppa Italia three times in his 21 years with the club.
