Danielle Carter’s goal delivered a record 14th Women’s FA Cup trophy for Arsenal as they dominated holders Chelsea at Wembley Stadium.
Carter, who clipped a first-minute chance onto the roof of the net, gave the Gunners a deserved early lead with a fine solo run and curled finish.
Asisat Oshoala then spurned three good chances to double Arsenal’s lead.
Fran Kirby wasted Chelsea’s best opening in front of a record Women’s FA Cup final crowd of 32,912.
The England striker lacked direction with her first-half strike after running through, allowing goalkeeper Sari Van Veenendaal to save at the near post.
Ji So-Yun also went close after the break, shooting wide following their first corner after 70 minutes but the Gunners were excellent value for the victory.
