Players and former staff of teams in the National Women's Soccer League (NWSL) have leveled several allegations and formal reports of sexual abuse, harassment, misconduct, and manipulation, as well as weight-shaming, verbal and emotional abuse, and racist and sexist remarks across its history. These allegations of crossing professional boundaries with players have led to formal investigations of and by the NWSL and many of its teams and coaches, most prominently during the league's 2021 season but including events dating to the league's inception and extending to its present.
