The deal with Mark Burnett Productions will see it continue until at least 2009. Jeff Probst will also stay in place as host.
Ratings for recent series have dropped from Survivor's height but it still attracted 15.2m viewers last year, leading the Thursday 8pm slot.
CBS reality chief Ghen Maynard paid tribute to Burnett and Probst and said: "Survivor is a show that defies ratings gravity.
"It is truly remarkable feat to be winning your time period in all ratings categories after 15 editions."
The 16th series will begin on February 7 while casting has started for the next.
