The 2015–16 season was Arsenal's 24th season in the Premier League and 96th consecutive season in the top flight of English football. The club entered the season as the FA Cup holders, and participated in the Premier League, FA Cup, League Cup, Community Shield and the UEFA Champions League. The season covers the period from 1 July 2015 to 30 June 2016.

Arsenal began their season with the Community Shield against local rivals Chelsea. The Gunners won the match 1–0, following a goal by Alex Oxlade-Chamberlain, who scored via a drive into the top corner. The trophy was Arsène Wenger's 15th in 18 years of being in charge of Arsenal, and presented Wenger with his first win against a side managed by José Mourinho after 13 attempts. Soon after, Arsenal began their 24th Premier League season at home to West Ham United, and inspired by the signing of goalkeeper Petr Čech, many believed Arsenal to be title contenders for the first time in 11 years. The club's solid pre-season form, however, fizzled out as they failed to win in their first two home games, with a 2–0 defeat to West Ham on the opening weekend, leaving them third-bottom, and a goalless draw with Liverpool, although Aaron Ramsey was falsely ruled offside for an early goal. With two tight wins at Crystal Palace and Newcastle United, Arsenal went into September with seven points. Arsenal did not make additional signings after Čech, leaving manager Wenger to come under fire from fans and critics.
