The 2023 season was the New England Patriots' 54th in the National Football League (NFL), their 64th overall, their 22nd playing home games at Gillette Stadium and their 24th and final under head coach Bill Belichick.

Following their Week 12 loss to the New York Giants, the Patriots failed to improve on their 8–9 record from 2022.

The Patriots missed the postseason for the second consecutive year (and third in four seasons).

Following a Week 17 loss to the Buffalo Bills, the Patriots finished last in the AFC East for the first time since 2000.

Belichick and the Patriots mutually agreed to part ways following the season's conclusion.

On a day where the team honored longtime quarterback Tom Brady in their halftime ceremony, it was spoiled by an Eagles victory.

The Patriots lost to the Raiders for the second year in a row, and had their worst start in the Bill Belichick era.

Chad Ryland missed a game-tying field goal with 6 seconds left to seal the defeat.

Also, the Patriots became the first team since the 1938 Cardinals to allow 10 or fewer points in three consecutive games and lose all of them.

However, the Patriots were eliminated from postseason contention when the Bengals defeated the Colts the following Sunday.

This marked the 3rd time the Patriots lost to the Chiefs since 2019, having not won against them since the 2018 AFC Championship game.

This was also Bill Belichick’s final game with New England, as he and the Patriots mutually agreed to part ways a couple of days afterwards.
