The 2018 Buffalo Bills season was the franchise's 49th season in the National Football League (NFL), and the 59th overall. The season also marked the fourth full season under the ownership of Terry and Kim Pegula and their second under the head coach/general manager tandem of Sean McDermott and Brandon Beane. The team previously finished with a 9–7 record in 2017 and returned to the playoffs for the first time after having not been to the playoffs since 1999.

After a 21–17 loss to the rival Miami Dolphins in Week 13, the Bills failed to match their 9–7 record from the previous season. They were officially eliminated from playoff contention the following week with a 27–23 loss to the New York Jets, ultimately finishing with a 6–10 record as numerous players from the previous season departed via trades, roster cuts or retirement. They went 4–3 in their last 7 games. This season was also notable for being the first season for quarterback Josh Allen and the last one for longtime defensive tackle Kyle Williams. As of the 2023 season, this is the only time where McDermott has not led the Bills to the playoffs as head coach. It is also the Bills' most recent losing season.

Until the 2022 season, this was the last time the Bills lost to the Dolphins.
