2014: Fourth Super Bowl win

Brady started the 2014 season with a 33–20 loss to the Dolphins. It was Brady's first opening day loss since the 2003 season. After going 2–1 in the next three games, Brady helped lead the Patriots to a seven-game winning streak. In that stretch, Brady had two games with four touchdown passes and one game with five. He won AFC Offensive Player of the Month for October. Brady clinched his NFL record 12th AFC East division title with a Week 14 win against the San Diego Chargers, later in the season. Brady was named to his tenth career Pro Bowl and was ranked third by his fellow players on the NFL Top 100 Players of 2015 list.

In a 35–31 Divisional Round win over the Ravens, Brady threw for three touchdowns and ran in a fourth, breaking Curtis Martin 's club record for rushing touchdowns in the playoffs; Brady also broke Joe Montana's record for playoff touchdowns with 46. After the Ravens scored on their first two possessions, the Patriots were quickly down 14–0, but would end up tying the game 14–14. Brady threw an interception at the end of the first half, which wound up leading to a Baltimore 21–14 halftime lead. Down 28–14, Brady engineered an 80-yard drive, culminating in a touchdown to Rob Gronkowski to cut the lead to 28–21. The Patriots tied the game once again at 28 off of a trick play where Brady passed laterally to Julian Edelman who then threw a 51-yard touchdown to Amendola. Ravens kicker Justin Tucker converted a 25-yard field goal to give Baltimore a 31–28 fourth quarter lead. Brady got the ball back, and threw a 23-yard touchdown to wide receiver Brandon LaFell to give the Patriots their first lead, 35–31, with 5:13 remaining. After a Duron Harmon interception and a Joe Flacco Hail Mary attempt failed, Brady clinched his record ninth AFC Championship Game appearance. It was his fourth straight overall. After a 45–7 blowout of the Colts, Brady advanced to play in his sixth Super Bowl, breaking a tie with John Elway for most career Super Bowl appearances by a quarterback.

In Super Bowl XLIX, Brady completed 37-of-50 passes for 328 yards, four touchdowns, and two interceptions. He guided a then-record ten-point fourth quarter comeback as the Patriots defeated the Seattle Seahawks 28–24 to give Brady his fourth Super Bowl ring, tying him with Joe Montana and Terry Bradshaw for most Super Bowl victories by a starting quarterback. He was named Super Bowl MVP for the third time, tying Montana's record. Brady's 37 completed passes in the game set a Super Bowl record at the time, which Brady himself would break in Super Bowl LI two years later.
