The three-year deal is thought to be worth over £10m and is being described as the largest single investment in British women’s sport by a business.
Under the terms of the agreement, the top flight league will be rebranded as the Barclays FA Women’s Super League from next season, with a £500,000 prize pot offered for the first time. Barclays will also become lead partner of the FA Girls’ Football School Partnerships which helps facilitate girls’ seeking to enter the sport from school.
Barclays chief executive Jes Staley said: "To be able to put our support behind women's football is a great initiative for the bank. The momentum is clearly behind the sport and we'll see women's football grow tremendously across the United Kingdom."
The FA has itself upped its investment in the women’s game as part of efforts to raise female participation in the sport.
Earlier this month Budweiser signed its first ever sponsorship of the women's game.
