Original Nike trainingsshirt AS Roma 2017/18

The 2017–18 season was Associazione Sportiva Roma's 90th in existence and 89th season in the top flight of Italian football. The club competed in Serie A, the Coppa Italia, and the UEFA Champions League, qualifying directly to the group stage after finishing runners-up to Juventus.

The season was the first since 1991–92 that Francesco Totti was not part of the first-team squad, having retired at the end of the previous season. On 13 June 2017, former Sassuolo coach Eusebio Di Francesco was appointed as Roma manager, replacing Luciano Spalletti, who left for Inter.

On 5 December 2017, the Stadio della Roma project – after experiencing five years of delays due to conflicting interests from various parties in the local government – was given the go-ahead to begin construction. It is slated to open in time for the 2020–21 season and will replace the Stadio Olimpico as Roma's ground.
