The 2015 season was the Seattle Seahawks' 40th in the National Football League (NFL) and their sixth under head coach Pete Carroll.

This marked the fourth consecutive season in which the Seahawks secured double digit wins.

In the Divisional round, the Seahawks fell behind 31–0 to the Carolina Panthers at halftime and ultimately lost 31–24, ending their hopes of becoming the first team since the 1990–1993 Buffalo Bills to appear in three consecutive Super Bowls.

In the first quarter, rookie Tyler Lockett returned a punt for 57 yards for a touchdown to give the Seahawks the game's first points.

The loss of their defensive captain was too steep to overcome as they would go on to lose in overtime, 34–31, after Greg Zuerlein hit a 37-yard field goal with 12:06 remaining.

After a tough opening loss to the St. Louis Rams, the Seahawks traveled to Green Bay to take on the Packers.

However, the Packers proceeded to score the final 14 points of the game and won, 27–17, sending the Seahawks to their second consecutive loss of the young season.

After playing (and losing) their first two games of the season on the road, the Seahawks went home to face the winless Chicago Bears, hoping to avoid an 0–3 start.

Tyler Lockett returned the second half kickoff 105 yards for a touchdown to give Seattle a 13–0 lead.

After easily defeating the Bears, the Seahawks remained at home to face the winless Detroit Lions.

Wilson was sacked and fumbled, and the Lions defense ran it back for a touchdown, cutting the deficit to 13–10.

Minutes after the game ended, the NFL VP of officiating ruled that Wright illegally batted the ball out of the back of endzone.

Had the call been made, a penalty would have been assessed that gave the Lions a 1st down at the spot of the fumble, plus half the distance to the goal (6–inch line).

Several comparisons were immediately made to the Seahawks' controversial victory over the Green Bay Packers in Week 3 of the 2012 season, which also happened on Monday Night Football.

After defeating the Bears and Lions (both winless teams) at home to get to .500, the Seahawks traveled to Cincinnati to take on the 4–0 Bengals.

In the 3rd quarter, a 23-yard fumble returned for a touchdown by Bobby Wagner allowed the Seahawks to take a commanding 24–7 lead.

After losing a heartbreaker in Cincinnati to the Bengals, the Seahawks returned home to face their second undefeated team in a row, the 4–0 Carolina Panthers.

After blowing four 4th quarter leads and only winning against two teams with losing records, the Seahawks traveled to Santa Clara to take on the 49ers.

Late in the second quarter, Ricardo Lockette left the game with an apparent injury after taking a brutal hit by Jeff Heath.

A day later, the Seahawks announced that Ricardo Lockette underwent season-ending neck surgery and miss the rest of the season.

After the bye week, the Seahawks hosted the Arizona Cardinals in their second Sunday Night Football game of the season.

Trailing 19–0 late in the second quarter, the Seahawks turned to fullback Will Tukuafu to give Seattle the first touchdown of the game.

Coming off huge home wins against the 49ers and Steelers, the Seahawks traveled to Minneapolis to take on the Minnesota Vikings.

The Seahawks defense held Peterson to only 18 yards and the Vikings' offense failed to score (their only points coming on a special-teams kickoff return), while Russell Wilson and the Seattle offense racked up 433 yards, five total touchdowns, and no interceptions.

Russell Wilson's streak of games with greater than a 135 passer rating continued as he again tied the franchise mark of five touchdown passes to go with zero interceptions.

After a huge win against the Ravens in Baltimore, the Seahawks returned home to host the Cleveland Browns.

With the injury of Thomas Rawls the week prior Derrick Coleman got the start at running back but Christine Michael took the majority of the carries.

In their final game of the regular season, the Seahawks routed the Arizona Cardinals 36–6, holding the Cardinals' then number one scoring offense to only six points, allowing the Seahawks to finish as the number one scoring defense for the fourth consecutive season, an NFL record.

The Seahawks fought back aggressively in the second half, cutting the lead to only one possession and holding the Panthers from scoring in the second half, but fell short of a victory after the Panthers successfully recovered an onside kick and kneeled out the clock, with a final score of 31–24.
