Hartley was signed by the New Orleans Saints on October 29, 2008 to replace Taylor Mehlhaff, who was released.
He played in his first game on November 9, 2008 against the Atlanta Falcons.
Hartley came out strong, booting 13 for 13 field goal attempts for the 2008 season.
He was expected to be the Saints starting kicker for the 2009 season.
However, Hartley was given a 4-game suspension after testing positive for a banned stimulant, Adderall.

Hartley remained inactive (while longtime Saints kicker John Carney handled the kicking duties) until the Saints' twelfth game of the season, against the Washington Redskins.
Hartley then kicked four field goals, including the game winning kick in overtime that allowed the Saints to preserve their undefeated record.
He missed the first field goal of his professional career in this game, from 58 yards.
He held the NFL record for most consecutive field goals made to start a career, with 16 until the record was broken in 2012 by Kai Forbath of the Washington Redskins.
On January 24, 2010, he made a 40-yard field goal in overtime against the Minnesota Vikings in the NFC Championship game to send the New Orleans Saints to their first Super Bowl.
He continued in Super Bowl XLIV, going 3-for-3 with field goals of 46, 44, and 47 yards.
He became the first kicker in Super Bowl history to convert three field goals of 40 yards or more.

The 2010 season began erratically for Hartley.
He missed 2 field goal attempts in the Saints' Week 1 home win over Minnesota, then made 3 kicks despite windy conditions in a Week 2 win at San Francisco.
 In a Week 3 match with Atlanta, he made a last-second field goal to send the game into overtime, but then missed a 29-yard field goal attempt in overtime that would have won the game.
 In response, the Saints re-signed John Carney, and Hartley was inactive for the next 2 games.
 With injuries mounting at other positions, however, the Saints decided not to continue carrying 2 kickers, cutting Carney and returning Hartley to his starting position.
 He later signed a contract extension that was reported to make him the highest paid kicker in the game.

Hartley missed the entire 2011 season after injuring his hip during a preseason game.
He was replaced by veteran John Kasay.
He returned as the Saints' kicker in 2012 and 2013 season, but struggled with intermittent bouts of inconsistency.
 After he missed two field goals against the St. Louis Rams on Sunday, December 15, 2013, one of which was attempted from only 26 yards,  he was released by the Saints on December 17, 2013 and replaced by veteran kicker Shayne Graham the same day.
