The new deal will keep the 36-year-old with the Cottagers until the summer of 2011.
Fulham said on their official website: “The club is delighted to announce that Mark Schwarzer has signed a one-year extension to his contract with Fulham.
“Ever present in goal last season, Schwarzer played a major role in the club’s outstanding defensive form during the 08/09 campaign.
“His performances over the course of the season were simply world class and were duly rewarded when he collected the Player of the Season Award.”
