Mason Walker Crosby (born September 3, 1984) is an American former professional football placekicker.

[4] While enrolled at Colorado, he displayed extraordinary leg strength, making a school-record 60-yard field goal against Iowa State in 2004.

[5] Crosby's 58-yard field goal against Miami in 2005 was the longest ever kicked in NCAA Division I-A football at sea-level without a tee.

Crosby connected on 66 of 88 field goals in total during his college career, and 30 of 34 inside 40 yards.

[7] He developed a reputation for kicking in the clutch, making 12 of 13 field goals in the fourth quarter, and a perfect 10/10 in the final 8+1⁄2 minutes of games.

[8][9] Crosby also served as the Buffaloes' kickoff specialist, where his knack for forcing touchbacks after touchdowns made him a fan favorite.

[18][19] Crosby entered training camp in a battle with incumbent placekicker Dave Rayner.

[20] In his first regular season game, Crosby converted all three field goals he attempted, including a 53-yarder and a 42-yard kick with two seconds left on the clock to help the Packers defeat the visiting Philadelphia Eagles 16–13.

[21] The kick was the first game-winner by a rookie on opening weekend since 1979 (when Matt Bahr achieved the same feat).

[22] Crosby was named NFC Special Teams Player of the Week (the first rookie kicker to receive this honor on opening weekend).

[24] He led all NFL kickers with 54 points and tied for the lead with 12 field goals as the Packers posted a 4–1 mark.

[25][26] For the 2007 season, Crosby led the NFL with 130 points scored and his 24 field goals ranked first in the NFC.

[33][34] In the first game of the 2010 regular season against the Eagles, Crosby kicked a field goal from 56 yards in the last seconds of the first half, his then career long and a franchise record.

[42] In Week 5, he equaled his then record distance on a 56-yard field goal on October 9, 2011, in the third quarter against the Atlanta Falcons.

[43] In Week 7, Crosby set the franchise record when he made a 58-yard field goal in the third quarter as part of a four-field-goal game.

[65] Crosby converted all 42 extra point attempts and added 33 field goals in the 2013 season, tying the franchise single-season record with Ryan Longwell and Chester Marcol.

[71] On January 18, 2015, in the NFC Championship, Crosby kicked a season-high five field goals against the Seattle Seahawks, including a 48-yarder to force overtime.

[72][73] In Week 2, Crosby broke Ryan Longwell's team career scoring record of 1,054 with his fourth field goal of the game against the Seahawks.

[82] On January 15, 2017, Crosby kicked two field goals, from 56 and 51 yards, in the final two minutes of the Packers' 34–31-second-round NFC Divisional Round against the Cowboys.

He also converted his 20th consecutive field goal in the postseason, surpassing David Akers's previous record of 19.

The Packers had been suffering difficulties with the longsnapper position and holder responsibilities changed hands several times throughout the year.

During a Week 10 matchup against the Chicago Bears, Crosby missed a 35-yard field goal off of an off-line snap that was then mishandled by rookie holder and punter Justin Vogel.

[87] After that game, Crosby only missed one more kick for the rest of the season, a would-be record at Heinz Field of 57 yards.

[88] Due to the Packers' loss of Aaron Rodgers for most of the season, defensive difficulties, and special teams miscues, 2017 would be only the second year Crosby had not played in a playoff game in his 10-year NFL career.

[90] In a Week 2 tie against the Vikings, Crosby made what appeared to be the game-winning field goal at the end of regulation.

[92][93] Crosby bounced back the following week, converting all three extra point attempts and all four field goal attempts, including a 27-yard game winner as time expired in a 33–30 win over the San Francisco 49ers, earning him NFC Special Teams Player of the Week.

[115] In the Divisional Round against the 49ers, Crosby had a kick blocked by Jimmie Ward at the end of the first half.

[123] On December 22, 2023, Crosby was signed to the Giants practice squad following an injury to kicker Cade York.

Mason's father, Jim, was a running back in college for the UTEP Miners and graduated from Texas Tech.
