On March 15, 2007, Curtis signed a 6-year, $32 million deal with the Philadelphia Eagles, including $9.5 million in guaranteed money.
 Curtis spent his whole career behind potential Hall of Famers Isaac Bruce and Torry Holt.
Now, free from their shadow, he set career highs in his first year with the Eagles and finished the year with 1,110 yards, 77 receptions and 6 touchdowns.
He was the eleventh receiver in Eagles history to reach over 1,000 receiving yards, and just the second to under Andy Reid.

Curtis had his best game on September 23, 2007 in the first half of a 56-21 Eagles win over the Detroit Lions.
His nine catches for 205 yards and three touchdowns tied Lee Evans for the most receiving yards during the first half of a game since 1987, when Steve Largent had 224 yards during a replacement game.
 Curtis finished the day with 11 catches for 221 yards and three touchdowns.
He became the first player in NFL history to recover his own team's fumble for a touchdown in back-to-back games when he fell on Reggie Brown's fumble in the 3rd quarter against the Buffalo Bills on December 30, 2007.
He recovered a McNabb fumble for a score a week earlier at the New Orleans Saints on December 23, 2007.
With his 77 receptions in 2007, became just the 4th wide receiver in Eagles history to record 75-or-more catches in a single season, joining Irving Fryar (88 in 1996, 86 in 1997), Fred Barnett (78 in 1994), and Terrell Owens (77 in 2004).

In 2008, Curtis only played 9 games in the season due to injury.
 He had surgery on August 21, 2008 to repair a sports hernia and was  inactive for the first six games of the season.
 He was also inactive at Washington on December 21, 2008, with a calf strain.
However, he had highlights against Cleveland, Curtis caught 4 receptions for 45 yards and a touchdown.
In the season Curtis caught 33 balls for 390 yards, and two touchdowns.
His return helped engineer an improbable run to the playoffs for Philadelphia, where the 5-5-1 Eagles would go 9-6-1 (6-3-1 in games Curtis played), and make it to the NFC Championship game.
He led the team with 122 receiving yards on four catches in the NFC Championship game at Arizona on January 18, 2009, which tied a franchise postseason record among wide receivers.

In 2009, Curtis played in the Eagles first two games of the season, before requiring arthroscopic surgery on his left knee.
He missed twelve games because of it, and did not return until week 15 against the San Francisco 49ers.
He was released by the Eagles on March 18, 2010.
He later attended workouts for the Giants and Lions but was not offered a contract.
